I am selling an inside out Bubbler I've had for YEARS! I paid around 350 for it but forgot about it in a closet after using it with a health stone. Not sure where the stone is now, but if you want to use one....it'll fit. I'm asking $100 shipped.....I will include the Vatra hard shell case for an additional $20. Piece will be thoroughly soaked and cleaned before shipping. I will consider ALL trades. Thanks!
