Wooden brooch/pin with butterfly clasp. Wood: Birch Dimensions: 4cm h x 4.5cm w Metal gift box: diameter 7 cm Info: The preservation of the trees and forests of our planet is absolutely necessary, which is why all the wood we use comes from sustainably, responsibly managed forests. We only use fast-growing tree species such as birch, maple, cherry, and walnut, as these are the most sustainable. These forests are harvested at the rate of their growth, which means that the forests from which they originate will maintain their supply and character indefinitely.
