Boundless CFV Mini Bubbler
If you want to add another level of sophistication to your Boundless CFV then this is the piece for you. This water bubbler fits straight to the top of your CFV instead of the regular mouthpiece. It then bubbles your vapor through the water chamber which cools your vapor and filters any solid particles out of it, meaning the coolest, cleanest vapor possible. Make the most of your Boundless and go water cooled.
