This is a RipTip rolling tip made in the Sensi Seeds x Death Row colourway: jet-black borosilicate glass with a neon green decal featuring the Sensi Seeds, Death Row, and RipTip logos.
RipTip has been making reusable glass rolling tips in Lakewood, Colorado, since 2015. The design that makes them work is a nine-hole vortex running through the length of the glass. The nine channels split the airflow as you draw, which cools the smoke and keeps the pull consistent. It also stops ash, tar, and resin from reaching your mouth, which is the main reason most people who switch from paper crutches don't go back.
This edition comes in size 11, meaning 11 mm in diameter, and is 1 inch long (2.54 cm). This makes the tip compact enough to roll with comfortably, wide enough for a proper draw.
Being reusable, it's a sustainable alternative to disposable paper filters, and cuts out a lot of single-use waste. A rinse with isopropyl alcohol is all it takes to keep it in good shape.
