The Klein Incycler Base is Prism's newest and premiere base. Because the water flows continuously through the base the pull on this thing is super smooth and it chugs super well. With a 14mm female joint, this base works perfectly for most bangers that fit it. In fact if you pair this with a bent mouthpiece you will have an excellent rig for concentrates. This piece however works phenomenally with non concentrate smoking material as well. The Klein Incycler base is a prefect addition to any Prism collection.
