Croll & Denecke Liquid Spruce Wood Square Soap Case - Perfect for storage & travel! Croll & Denecke have created this square soap dish from liquid wood and the off shoots of the spruce tree therefore making it extremely eco friendly. Liquid wood is made from a leftover part of trees that is unused during the paper-making process – over 100 million pounds of its main ingredient are created as a simple side-effect of the existing pulp (paper-making) industry. This leftover is combined with natural resins, flax and fiber that can be injected into moulds. Plastic Free Eco Friendly Made from the off shoots of the Spruce tree The Croll & Denecke liquid wood products are made in Germany, are biodegradable and do not contain any plastic.
