This stainless steel holder comes complete with an attached bottle opener on a split ring and features a neoprene liner on the inside to protect and insulate glass bottles, a screw-on top and bottom and the room to handle almost any 12 oz. bottle. Hand wash is recommended. After each use, wipe away any liquid and store the pieces separately to ensure that the neoprene liner dries completely. The item is intended to hold bottles - do not fill directly with liquid. Please remove both the top and bottom to insert the bottle.
