This is a very unique storage bottle for carrying 8 oz. of extra Denatured Alcohol for any of your alcohol stoves. It has a twin neck which allows you to fill or pour from one side. Lose the measuring cup and potential mess; measure and pour using one container. The twin neck measure and pour bottles require a simple squeeze to get just the right amount of liquid into the filling dispenser chamber. Now you're ready to pour. Graduated in 1 oz and 50 ml increments on the side of the bottle, or measure 1/4 or 1/2 oz with the dispenser chamber.
