This eye-catching ice prism is a stunning way to decorate and chill drinks. Simply fill the molds with water using the funneled filling points, and then freeze. The BPA-free silicone tray is stabilized by a rigid support structure, and the dual-sealing design prevents liquid from leaking out, ensuring easy transport from sink to freezer. When ready, the large geometric ice cube melts slowly and evenly, chilling drinks perfectly without diluting them.
