A straightforward 12" straight-tube water pipe made from borosilicate glass by HMP. The straight tube design keeps things simple: easy to fill, easy to clean, and easy to see the water level. At 12 inches, it's a mid-size piece that fits comfortably on a desk or shelf without taking up too much space.

The tube includes a built-in ice pinch, a set of notches molded into the glass that hold ice cubes above the waterline. This cools the smoke as it travels up the tube, resulting in noticeably smoother draws. Borosilicate glass is the same heat-resistant material used in lab glassware, so it handles temperature changes from ice and regular use without cracking.

The clean, minimal design means there aren't a lot of hard-to-reach chambers or percolator arms to scrub. A straight tube is one of the easiest bong shapes to maintain; a brush and some cleaning solution go a long way.

• Straight tubes are among the simplest bong designs to clean. Fewer internal chambers mean fewer places for residue to build up.
• The ice pinch is molded directly into the glass, not a separate attachment, so there's nothing extra to lose or break.
• Borosilicate glass is more resistant to thermal shock than standard glass, which matters when you're dropping ice into the tube.
