Includes 1 premium durable foam floating blue and black drink holder (tumbler not included). Compatible with Tervis, YETI, Ozark Trail and other tumblers, and fits most cans and water bottles. Note: only fits tumblers that will fit halfway down into opening. Deluxe premium foam float has been designed to keep your tumbler upright even in wavy water. Convenient tether hole lets you always keep your tumbler floating nearby (tether or rope not included). Special gripping teeth designed to fit tumblers 16 ounces to 30 ounces: Note that the opening size is very important! Please check your tumbler to make sure this float will work for your tumbler.
