OXO Good Grips Covered Silicone Ice Cube Tray This tray has one tier and makes 6 ice cubes. The ice cube size is 1 3/4 inch (approx. 44.45mm) cubes. The design is leak-resistant and easy to use. I used it once, and it has no noticeable scratches or stains and is still in good condition. I will ship it after washing and disinfecting it with alcohol, but please wash it before use. If you have any questions, please feel free to comment.
