Make 30 ice cubes on a stick at a time: you'll get 3 ice cube trays, each making 10 handy ice cubes on a stick. You'll always have perfectly shaped ice cubes when you need them. Fits the mouth of a water bottle: finally you have ice sticks that fit water bottles and standard sports bottles. Measuring approximately 3 3/4" long and 3/4" in diameter, the ice stick slips easily into most water bottles for quick and easy hydration and hassle-free cooling. Freezes quickly: BPA-free silicone tray makes it easy to freeze and easier to get the ice out. Remove only the ice you want. The narrow ice stick freezes faster than many ice cube trays. Fun for children: you get every bright colour: orange, blue and green. Fill with juice or fruit to create a water enhancer. Children will love using these to make ice cubes, popsicles or just play with the craft dough to create unique shapes.
