We have only the Compact size in stock: 4.6.26 only one left.

The MB5 is a lightweight fiberglass case made for screw bell French horns by Marcus Bonna in Brazil.  The fiberglass shell is surrounded by a nylon cover that is easily removed if repair or replacement is ever necessary.  The MB5 case includes backpack straps, a shoulder strap, several movable foam pads, storage pouch, a double mouthpiece pouch and ID tag. 

The case weighs 7.0 lbs and the dimensions are 23x14x8.5".

Two small interior spaces will hold your small accessories.  The lid includes storage room for two mutes.  The exterior has a small accessory pocket at the top of the lid and a sheet music pocket on the back near the strap mounting rings.

This case protects your horn with a plush interior and a snug fit for the horn body.  The body straps down to the floor of the case to prevent movement.  The bell flare slides into a padded sleeve that rests on top of the body and is pinched slightly when the case is closed.  Truly, we have feared damage from having the bell flare located there, but it never happens.  Never have we heard of such a bell injury to a horn traveling in an MB5 or similar case.  The caveat is that these cases are designed for use as hand luggage, and are not to be trusted to checked baggage or airport baggage handlers. 

This case actually comes in 3 sizes:

  • Standard:  fits nearly all double horns of normal size, Conn, Yamaha, Hoyer, Holton.  Now fits the Alexander 103, though the case is larger than it needs to be
  • Compact: This case is about 2" shorter and has a bit less storage inside.  Fits many Kruspe and Alexander style horns, maybe others.  For Alexander, see the MB5 Baby model.
  • XL: The shell is the same as the standard model, but the interior accessory compartment is smaller and the brace near the bottom to support the horn body is moved outward for larger horns.  Note:  New models a movable interior brace so you should be able to fit a variety of horns into the standard case.  Large wrap Geyer style horns like a Hoyer G10, Duerke LDx5, and Atkinson may be better in the XL

Instruments shown in the photos are a Paxman Series 4 and an Alexander 103.

As with all Bonna cases, many colors are available.  Given a bit of waiting, we're glad to offer this case in any single or two-tone color scheme that you'd like.  We receive shipments four times a year, so 30-90 days is a common wait time.

We try to stock several color combinations:

  • black nylon
  • black & blue nylon
  • black & green nylon
  • black & burgundy nylon
  • black & turquoise nylon

Other colors available include red, yellow, orange, light blue, light green, dark green, purple, grey and pink.

A leather outer cover is also available by special order.  See the drop down menu for pricing.  The leather adds less than a pound of weight.  The leather is stylish and may wear a bit longer than nylon, but you will get many years of use out of either.  The full spectrum of colors is available for leather cases.  Carbon shell is available, which saves less than a pound, but significant weight.

Compared to the MB7 case, this MB5 may be slightly more comfortable to carry as a back for some players, especially those of the petite size, due to its symmetry.  The MB7 may be more comfortable carried as a single shoulder strap case.

Weight: 7 lbs, 12 oz

Dimensions: 8x15x24"

The Toy Annie Always Comes Back To
Size: X-Small, Color: Pink
⭐⭐⭐⭐⭐ These have become one of Annie's all-time favorite toys. Annie is a tiny 4-pound dog, and she can be surprisingly picky about toys. She has a basket full of options, but she consistently comes back to her nubby Nylabones. I think the size and texture are a big part of why she likes them so much. They're easy for her to carry around, chew on, and play with by herself. Whenever I buy a new one, it quickly becomes part of her regular toy rotation. As a small-dog owner, I appreciate finding toys that are appropriately sized and actually get used instead of being ignored after a few days. If you have a tiny dog who loves to chew, these are definitely worth trying. They've been a favorite in our house for a long time.

Dogs love these!
Size: Small, Color: Pink
My miniature Goldendoodle puppies love these! The only drawback is after several weeks of chewing, the bones develop pretty sharp edges long before the actual bone has been worn down. At that point, they are dangerous for the dog’s gums and must be thrown away.

🦴 Micro Bone, Major Relief; Perfect Puppy Teething Chew Toy
Size: X-Small, Color: Blue, Size: X-Small, Color: Blue
🐾 Hi, I’m PVD; teething survivor, nub enthusiast, and gum massage advocate. This tiny blue bone was my day-one favorite from 8 weeks to 5.5 months, it handled every chew session, tantrum, and tooth eruption with dignity. I’ve officially “aged out,” but I still salute it. ⭐ Why it earned 5 stars: ✔️ Perfect XS size for toy breed jaws ✔️ Soft on sore gums, durable enough for dramatic chewing ✔️ Ridges + nubs = mouth spa treatment ✔️ Chilling it = elite teething relief ✔️ Kept me busy and prevented chewing on illegal things (furniture, shoes… mother) 🌀 Why I’m now gracefully retiring it (but still recommending): ✘ Jaw strength and confidence grew but I didn’t vibe with the larger size versions (tried and rejected them with judgment) ✘ Texture now too gentle for my post-teething chew style ✘ Advanced chewers may get bored once the rage-chewing era passes ✘ I get gum relief via Nylabone Nubz edible chews now Best For: • XS-Small breed puppies, especially under 5 lbs • Teething stages + gum relief • Delicate chewers or fur babies still in the love-bite phase • First-time puppy parents (trust me, this bone prevents household drama!) • 8 weeks–6 months old 🚫 Not for adult teeth or advanced chew techniques. 📝 Final Re-Barks: Iconic starter bone for toy breed pups. Affordable, safe, and genuinely soothing during teething chaos. It carried me through the hardest months (and saved several legs; both human and furniture). I’ve outgrown it; but I’ll forever endorse it for the next generation of tiny chewers. — PVD (Tiny Tooth Graduate, Former Chew Therapy Success Story 🧊🦴)

Nylabone Puppy Treat Starter Pack - A Mixed Bag of Delight and Disappointment
Size: Small, Color: Blue
I recently purchased the Nylabone Puppy Treat Starter Pack for my adorable 5lb puppy, and overall, I have mixed feelings about this product. While I was initially satisfied with the variety pack, one of the bones in particular left me disappointed due to its lack of durability. Let's start with the positives. The Nylabone Puppy Treat Starter Pack comes with three different toys: a blue puppy teething toy, a nylon dog toy, and a chew treat. This variety is great for keeping my puppy engaged and entertained, especially during the teething phase. The blue puppy teething toy is specifically designed for soothing sore gums, and my puppy seemed to find great relief when chewing on it. It has a pleasant texture that is gentle on the teeth and gums, making it an ideal choice for teething puppies. The nylon dog toy included in the pack is durable and sturdy. It has a satisfyingly textured surface that provides an excellent chewing experience for my little furry friend. The toy is designed to withstand the strong chewing habits of puppies, and it has certainly proven to be long-lasting compared to other toys I've tried in the past. My puppy enjoys gnawing on it for extended periods without any signs of damage. Now, let's address the bone that failed to meet expectations. One of the bones included in the pack was devoured by my puppy within a single evening. I was taken aback by how quickly it was consumed, especially considering my puppy's small size. While the other bones in the pack held up well, this particular one lacked the durability I had hoped for. I understand that puppies have strong jaws, but I expected the bone to withstand more than a few hours of chewing. Despite this disappointment, I must mention that the bone did not cause any harm to my puppy. It is important to supervise your puppy while they chew on any toys, especially if they have a tendency to swallow large chunks. In this case, I was fortunate that my puppy did not experience any adverse effects after consuming the bone. However, it's crucial to exercise caution and ensure that your puppy doesn't ingest anything that could potentially be harmful. Overall, while the Nylabone Puppy Treat Starter Pack has its upsides, I cannot ignore the fact that one of the bones failed to meet expectations in terms of durability. However, the other toys included in the pack provided a satisfactory experience for my puppy, and they have proven to be long-lasting. I would recommend this product with the caveat that you closely monitor your puppy's chewing habits and potentially avoid the bone that didn't hold up well in my particular case.

⭐⭐⭐⭐⭐ Great for teething puppies
Size: Small, Color: Pink
I purchased the Nylabone puppy chew toys for my teething puppy, and they’ve been a big help. The toys are the perfect size for a young puppy and feel durable without being too hard. My puppy enjoys chewing on them, and they’ve helped redirect chewing away from furniture and shoes. I also like that they’re designed specifically for puppies, so they’re gentle enough for growing teeth and gums. The variety in the set keeps my puppy interested, and the toys have held up well with daily use. They’re easy to clean and feel safe to give to a puppy. Overall, these are great chew toys for puppies. They’re effective, well made, and helpful during the teething stage. I would definitely recommend them to new puppy owners.
