Thank you for viewing. ★Please be sure to read the profile before purchasing. [Product Condition] No box or instruction manual, has scratches and dirt. Works well. This is an old kaleidoscope I found while organizing my parents' house. It has scratches and dirt, but I was able to see various shapes. Please check the images for details. The length is about 21cm, the side length of the triangle is about 3.5cm, and the height is about 3cm.
