This environmentally friendly cup is made from biodegradable bamboo fibre and features beautiful illustrations of popular garden birds: the Great Tit and House Sparrow by artist Elwin van der Kolk. A stunning design for both in the home and outside picnics. Just one of the products in his bamboo range so look further for matching items. This item is dishwasher safe, but not suitable for use in a microwave. The capacity of the cup is 250ml. Elwin van der Kolk, the Dutch biologist and natural painter, was fascinated by the nature around him at a young age. He spent a large part of his childhood watching and drawing birds. In his drawings he tries to capture wildlife in such a way that the viewer is encouraged to admire and protect nature.
