This 18mm Glass Stopper fits any 18mm female glass connection. It can be used as a carb for glass with multiple connections, or just to plug up a connection when not in use. It’s also a great accessory when cleaning your glass pieces. Use this stopper to keep any water or cleaning agents contained as it soaks, or while giving it a good shake.
