The CLIP & CLOSE ice cube tray has space for up to 24 ice cubes – just tilt the box slightly after filling it with water to make sure the cubes end up the same size. Thanks to the special freshness seal, the container is 100% leak-proof. No spillage. No leaks in the freezer. The flexible base makes the ice cubes extremely easy to remove when frozen. And of course, this CLIP & CLOSE is also BPA-free, making it safe to use for baby food. It’s also great for storing small portions of herbs and pesto.
