Hand made out of borosilicate glass. Kiln annealed for extra strength. Better than OG rip off... Reusable and easy to clean. Tips are 7mm wide. Tips can be rolled in your favorite paper and even in rolling machines. Helps keep the smell off your fingers too! Once you try one you won't want to smoke without it! Please specify which tip you would like or you will get one of each...  I can't take color requests, I depends on what tubing I have at the moment....
