A roach clip is a clip, or holder, that is attached to a cigarette (usually a marijuana cigarette). Its purpose is to let the smoker smoke the last piece of the cigarette ("roach", derived from the Mexican Spanish slang term for marijuana, cucaracha, "cockroach") without burning his or her lips or fingers, and to facilitate passing around the roach without dropping it.

The "classic" or most familiar roach clip is the surgical hemostat, essentially a lightweight needle nose plier with loop handles and an ability to lock closed, originally designed to clamp closed blood vessels during surgery. Their size (usually four or six inches in length) and shape (available with straight or bent tip) makes them ideal for holding the burning end of a joint -- a marijuana cigarette -- to the lips without burning them. They are popular enough as "roach clips" to be sold at "head shops", or purveyors of drug paraphernalia.
Another popular type of roach clip is the alligator clip. Alligator clips are generally smaller in size (from one to three inches) than hemostats, but like hemostats they have the feature (in this case provided by the force of a spring) of being able to clamp onto the roach without any sustained effort on the part of the smoker.

Some choose to go the makeshift route, and use very common household items such as paperclips and keys, often when the better alternatives listed above are unavailable. Most people now use a filter made from a piece of cardboard or hard paper, in sort of a mock attempt at a cigarette filter.
Most naturally fitting the bill as a roach "clip" is the cigarette holder.

As we are makers of bongs, bubblers, pipes, one-hitters and other glass smokeshop goods, we can modify any of our bongs or pipes according to your needs. We make glass pipes and water bongs for a long time and our production methods are traditional and proved. It is a precise hand work and art glass blowing. See video from our glassworks!
Bongs offered in our bongs shop are light, but also hard and durable, made from Pyrex (PHX). The pipe shop offers glass pipes made from the same material. Our glass products are very popular also for their color changing effect (CCG), which is done by adding raw silver on the glass surface in high temperatures. Bongs, pipes and one-hitters with this effect are very cool and look crazy.
You can also get a free pipe or free one-hitter with your order, and you will get a set of free jax screend with every bong you buy here!
