This product is made of 100% wood and finished with natural wood color. The storage box is a perfect addition to either your indoor counter top, desktop, and window sill for any small stuff or your outdoor garden and patio for tools, and for Fragile Shipping & Storage. A lid with hinges makes opening and closing easier; the lock is not included, but can be added to keep stuff untouched and safe. The half-inch thickness, along with a cut-out design on the side panels, ensures a strong, sturdy structure.
