Ultra light. Ultra practical. Ultra cool.
The Twister Spring Pipe by Sector 7G is a really simple yet superb design. Made from high grade stainless steel, it is extremely light and, due to its spring barrel, it can fold all the way over so that the mouthpiece slots into the bowl.
As you toke on the Twister Spring Pipe, a small nudge of the barrel allows air to enter through the spring gaps, acting much like a rush hole.
In folded form, the Twister Spring Pipe can be attached to a chain or your keys. Like this, it can't be identified as a pipe and is easily transportable.
The Twister Spring Pipe also comes in an attractive felt pouch.
