The Yakisugi Ring is handcrafted with a real wood exterior and an interior made with our proprietary forged carbon. The ring is named for the Japanese method of wood preservation Yakisugi, known in the west as Burnt Timber. This method chars the wood just enough to carbonize it without causing combustion. The carbonized surface creates a protective layer, making the wood more durable. 

Although we do seal every ring, they are not intended for prolonged submersions in water. Remove your ring when using harsh chemicals like cleaners and solvents. The finish could scratch against materials like stone or concrete. Like all rings, it should be removed when doing activities like weightlifting or rock climbing.
