Due to popular request, certain tubes are now sold TUBE ONLY. The housing assembly will be sold separate so you can choose the exact look/style you want for your setup. Prices for TUBE ONLY listings reflect this change.

It's always a good day when an old school prototype comes to life!

The Piranha is here! With an hourglass-like shape that supplies a comfortable grip along the tapered, bottom portion of the tube. Although it may look a little rough around the edges, or even like the teeth from a piranha fish if you look hard enough, the high polish finish will feel smooth and soft as long as it's clean!
