Cute!
Size: 4 Pack
Pretty good! Closed and open just fine. They wash well and dry fast. Enough room to add what's needed. Easy for adults to open but kids will need help. Color is just like the picture shown! Overall I like them so far!

Highly recommended!
I ’ve been using the Age Defense Face Sunscreen Lotion for a while now, and it has quickly become a staple in my skincare routine. The formula is lightweight, non-greasy, and absorbs quickly without leaving a white cast, making it perfect for everyday use. It provides broad-spectrum protection, shielding my skin from both UVA and UVB rays while also containing anti-aging ingredients that help keep my skin looking youthful and hydrated.
One of the standout features is its moisturizing effect—it doesn’t dry out my skin or clog pores, making it suitable even for sensitive skin. I also appreciate that it layers well under makeup without pilling. The added antioxidants are a bonus, offering extra protection against environmental stressors.
The only minor downside is that it has a slight scent, which might not be ideal for those who prefer fragrance-free products. However, the scent fades quickly and isn’t overpowering.
Overall, this sunscreen is a great choice for anyone looking for reliable sun protection with added skincare benefits. It’s effective, comfortable to wear, and leaves the skin feeling soft and smooth.
