Work of fish emergency exit design. I attached a photograph to the balsa material and finished it as a picture frame. The size is 13 cm x 8 cm. Wall mount bracket included. Because it is very lightweight, you can paste cellophane tape, double sided tape etc on the back and paste it on the wall. (Please be careful not to peel off the wall surface.) We set it as 6 days from customer receipt to shipment. It is strictly prohibited to get wet.
