The 26oz stainless steel vessel maintains refreshingly cold beverages for up to 30 hours, fits in standard cup holders for on-the-go convenience, and is top-rack dishwasher-safe for easy cleanup. It has a carry handle lid, silicone base for stability, and patented twist-on agitator enhance the experience. Fans will feel the difference between a 4D Ice Shaker because of its raised full color print. Made by Wincraft.
