The metal pipe Twister consists of a mouthpiece, pipe bowl  and a metal spring. All the pieces are made of metal, but the drawtube is a metal spring system and you can form it with little effort. This is practical, because you can preserve the Twister in the included bag
On the bottom of the pipe bowl, there is an engraved motif. This is the same motif that you can find on the bag. In the bag you'll find some more informations.

Diameter of pipe bowl: ca. 1.0cm
Length: ca. 12cm
