100% recycled glass with maple wood top and 100% leather trim. Our sustainable Stowe Eco Glass Bowls are FSC (Forest Stewardship Council) certified, meaning every piece of wood we use is sourced from responsibly managed and environmentally conscious forests. Due to the nature of recycled glass, minor imperfections and variations may exist. Maple wood is untreated natural wood, meaning each piece is entirely unique. Wood may expand and contract when placed in warmer, colder, or more humid environments for extended periods of time.
