G-Spot Glass Rubber Carb Stopper
A carb stopper is the opposite of a carb hole. If you own a piece that has a carb hole on it and you don’t like to operate your pipe that way, grab this simple accessory and your problem is solved. It’s made from red rubber and will work with basically any bong that has a carb hole.
It’s also super useful when you need to clean your piece and close off any holes when shaking it with the cleaning solution inside.
