Size: Outer dimensions approx. 21 x 10.5 x 5 cm (thickness) Inner dimensions approx. 18 x 7.6 x 3.6 cm (depth) This box was made to store a 6-sun *kakocho* (a ledger for Buddhist memorial services). Paulownia wood has the characteristic of absorbing and releasing moisture from the air as if it were breathing, which helps to maintain a constant internal humidity. This makes it suitable for storing items that are particularly sensitive to moisture. It is ideal for keeping your precious items safe. A cloth to wrap the *kakocho* is also included.
