This is my outside-in bong from Hamms waterworks. It is basically a 3 hole disk diffused incycler with 14mm joint. The level of quality and craftsmanship in this piece is probably the best I’ve personally had in my collection, the base is an inch thick and every weld is perfect. It functions amazingly well for such a small piece(stands at 14.5 inches) and is a genuine pleasure to watch function. The 14mm joint can be slightly restrictive for my slide choice so I have a hamms 14-18mm dry catch to go with it. No slide included.
