These bongs do without the small carb hole in the glass body. Smoke them in one go or via the classic lift-off - by lifting the bowl piece. A bong without a carb hole is the only thing for many smokers. Especially when dabbing, the extra opening is not necessary, because with a compact oil rig it is already sufficient to regulate air pressure and oxygen supply by means of a Carb Cap or a Carb Cap Dabber.
User tip: To smoke a bong without a carb hole in the best possible way using the lift-off technique, you should get the right bowl to go with it. The best choice is a bowl made of extra thick glass with a handle, Maria rings or a similar grip area that protects your fingers from burns caused by the heated glass. Alternatively, bong bowls made of silicone or wood are also perfectly suited for this purpose.
