These stunning handmade, solid oak Lichtenberg coasters showcase the beauty of electricity as 2,000 volts create unique, tree-like burn patterns in the wood. Each piece is completely individual, making these coasters truly one of a kind. Available in sets of at least two per colour, they measure approximately 10x10 cm (4x4 inches) and are about 2 cm (0.8 inches) thick, though thickness may vary to ensure the best quality. Our best-selling colours include Emerald, Royal Lapis, and Autumn Leaves. Please refer to the item images for available colour options. Customers often but coasters individually as a gift.
