T3 Cascading Waves Reversed Tapered Barrel-attachment only **For sale is the barrel attachment piece only.** The compatible base unit is the T3 Convertible Base unit, which is not included in this listing. I tried it twice (about 20 minutes total usage), so I know that it functions properly. I have wiped it down with an alcohol wipe. I'm selling it because I have several other T3 barrels that I use more often than this one. Please feel free to ask any questions you have, because all sales are final. I want you to be happy with your purchase! I will ship to Paypal confirmed addresses within the U.S. and use USPS.
