Aw... so cute! This is a half scale version of the 7x7 Corner Room Box. Overall 4" wide x 4" deep x 5" tall. The height from floor to top of wall is 4-1/2".
Also shown with the (larger) Half Scale Tall Corner Room Box.
This comes as a flat kit, but easy to put together with just a bit of glue.gryGD 180708new GND
