Welcome to the shop! 1. Each tray makes 7 dice-shaped ice cubes. One each of the standard RPG set – 1d4, 1d6, 1d8, 1d10, 1d%, 1d12 & 1d20. 2. With the silicone trays in place, attach the lid of the mold to the base. Fill the tray with water through the built-in funnel. 3. There are small air holes at the top of each mold; you'll know when each dice mold is full of water because excess water will drain through these air holes. Once full, place in the freezer. 4. There are four parts to the ice cube tray. The two case parts are made of BPA-free, recyclable material, and the two molds are made of food-grade silicone. 5. Easy to Use & Clean: Flexible, non-stick silicone material makes releasing ice cubes effortless. It features a smooth silicone surface for easy cleaning, adding to its convenience.
