We have partnered with Ducks Unlimited to create a mold for the outdoorsman. Ducks Unlimited is a grassroots organization that works with partners like private landowners, corporations, and government agencies to protect habitats for breeding, migrating, and wintering waterfowl. We wanted to capture their iconic logo in ice for outdoorsman to enjoy at home or in camp with their favorite beverage. • Package includes: 1 tray containing 4 large molds • These reusable tray molds are made from BPA free and food safe silicone • Fits glass with 3" diameter or larger. Perfect for single or double old fashion glasses • Easy to use—simply fill with water and freeze! Once frozen, to help release the ice from the mold, run silicone side of the mold under warm water for 30 seconds to 1 minute until ice easily releases. • Hand wash
