Small-sized Scandinavian monotone panels. Originally priced at 1990 yen. 12cm tall, 12cm wide, 1.8cm thick, set of 3. Since it's a set of 3, you can use them in various spaces. Hang them on the wall by inserting two push pins horizontally and hooking the frame on the back. You can prevent them from slipping by inserting the push pins slightly from above. I bought these on Mercari as a gift, but I didn't use them, so I'm selling them.
