The Stone Diffuser with box by @aroma is a custom-made wooden box and tray storage for the Stone Diffuser. The custom-made box is made from Japan's Kiri tree (also known as Paulownia tomentosa). It serves as storage and a removable wood tray to lay beneath the stone. The Stone Diffuser is made of clay in one of six ancient Japanese kilns, moulded and polished by hand. The Stone Diffusers' soft round shape gives a natural finish perfect for any space.
