This Skyglass-piece is a slight twist on the traditional design, with an extra 8" of tubing to let the smoke flow through. Basically, this awesome new-design provides a more stable beaker-bottom base(that features bubbled-out eges instead of sharp angles)that allows you to decide if you're only looking for just the right-sized draw or that power-house that you know will leave you gasping for air; with constant and steady air-flow, it's easy to measure exactly how much smoke you're allowing to pass through the clear glass. 5mm-thick all-around, Skyglass surprises with another simple design on a piece that still provides all the enjoyable smoking-experience and durability of a leading-brand and more.
