Ibili ice ball molds made of plastic with silicone seals. A large ice ball keeps the drink cold for a long time. You can fill the mold with plain water, or add fresh berries, mint leaves or lemon slices. Ice balls also effectively cool your cold brew coffee or tea.
Please Note! Do not fill the ball completely full with water, the water will expand as it freezes. Also, when lifting a filled ball, carry it from the bottom so that it does not open.
