I somehow lost the mouthpiece for my pen and was heart-broken, until I found this replacement piece on DopeBoo. Now I can keep using my favorite pen!
The mouthpiece works perfectly and was easy to replace. My pen's now as good as new.
I picked up an extra mouthpiece just in case I lose the original one. I lost stuff all the time, but this way I won't have to wait if I do lose a piece.
