WWF Partnership – Give back to the nature! One box at a time! The World Wildlife Fund for Nature is an international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. This has inspired Crystal Direct Trading to support WWF. Our Crane Crystal range highlights various endangered species, we hope to make a difference and create awareness of these land and sea creatures. The Crane Crystal range pairs endangered species with crystal glasses that show similarities in shape and function. We commit to using only the best quality crystal in our glassware and recyclable packaging, produced in factories that are also eco conscious. Crane Crystal is free of pollutants, naturally oxygenates the liquid content of the glass. The Crane Crystal range is lead-free, made from best crystalline sand. Join us in giving back to nature – one box at a time! Your purchase contributes to this conservation effort.
