I think this is good for storing magazines, newspapers, children's school documents, etc. It can be used as is, but metal fittings are attached to the back so that it can be hung on the wall with pins or screws. Approximate size: Width: 30cm Height: 30cm Depth: 12cm Inner dimensions: Width: 28cm Depth: 10cm If you want to install it on a front door or refrigerator, you can change the back to a strong magnet, so please let me know via message. Thank you for your understanding of handmade items.
