When turning joint or blunt, one of the most important things you will need is a filter, also known as a crutch. This can be anything – from hastily torn scrap paper to branded thin cardboard crutch sheets given out by pharmacies.
You can look for glass tips for joints at https://airstewardtips.com/ which helps to roll the little paper or cardboard and forms a tip for joints that you hold at your fingertips. It aims to keep plant matter out of your mouth when smoking, and allows you to fully suck in the joint without burning your fingers or losing any of the ingredients.
Glass filters serve the same function, but with a few added advantages:
Convenience: The glass filter will no longer scratch the appropriate sheet of scrap paper, or you won't have to remember where you put the crutches.
Smell: One of the worst things about the joints is that your fingers smell because the smoke hits your skin directly when you inhale. The glass filter creates a barrier that reduces pouring. Your skin still smells of smoke around it, but it's not harsh.
Classic: Joint and blunt, well twisted with a filter tip, looks better. There's also the fact that washing them makes much cleaner than sucking smoke through the paper. Your joints will also smell better, making them an even more classy experience than your regular joints.
