The mouthpiece for this bong is hidden by the glass suds near the top of the mug. The pipe has a 14mm female joint, and the 90 degree joint ends with a diffuser inside the body of the mug. This helps the smoke reach an optimal temperature while also filtering as much of the ash as possible. Each component of the mug is appropriately colored, so the suds are finished with white coloration while the mug itself is a transparent amber color just like a real mug of root beer.
Even though this piece is small, it can still pack a punch. Of course, instead of delivering a smooth dram of refreshing liquid, it produces perfectly cooled smoke with a taste that's true to the original dry herbal material. Since the piece is made entirely out of glass, you can use hot water with some chemical cleaner to help restore the piece to its original condition. No collection of artistic glass pipes would be complete without one of these bongs.
