Fill this clear Tritan Flip & Sip with your child's favorite beverage. It features a waving mermaid swimming in seaweed. It doesn't hold odors or stains, is shatter- and scratch-resistant, and is see-through for those who want to know what's inside. Comes with a removable carabiner so it can be attached to a backpack. Wash all parts by hand and rinse well before first use to preserve the life of the graphics.
