Colibri Silicone Straws are made in Canada using 100% silicone. They are 10″ long, BPA-free and tested to meet Health Canada and FDA standards. The stopper ring at the bottom makes them great for using in tumblers. These straws are dishwasher safe, can be washed in the sink or boiled to sterilize. Included with the set is a straw cleaner brush (also manufactured in Canada) which features a stainless steel handle and self-healing nylon bristles. The cleaner can be washed in hot water and is dishwasher safe!
