Native to the moist bottomlands in southwestern Canada, scattered in shallow valleys and waterway borders. The black walnut tree is renowned for its dark and lustrous heartwood used for high quality furniture and veneer. Each of our seamless diffuser is handcrafted by a skilled artisan from a single block of fine wood. It absorbs essential oils to naturally provide a serene environment by slowly dispersing vibrant aromas in smaller areas. Elegantly designed, this diffuser doubles as a classy decor piece. No cords, plugs, or electricity is needed for use. Best for bedroom and workspace, simply add 3 - 6 drops of your choice of pure essential oil on the top platform for 8 hours of vivid aroma. To avoid commingling, wait 72 hours for scent of one essential oil to completely dissipate before adding a different scent. The aroma can reach up to 10 - 12 feet for a Large Walnut Diffuser. A Small Walnut Diffuser diffuses 8 - 10 feet.
