OXO Good Grips Ice Cube No Spill Tray Green

Keep bottles cold with sticks that fit through narrow openings. Regular ice cubes won't fit through openings in most water bottles, but narrower ice sticks are shaped to slide through tight spaces. After filling Tray, cover with the silicone lid to seal in water and keep out odors. When lid is sealed, Tray can be stacked or stored at any angle in the freezer.
