This is a 2-way pianica case. I purchased this handmade item and used it to hold a YAMAHA pianica. Flat: 23 x 54 cm Three-dimensional: 19 x 48 x 6 cm (depth) I used it for two years in kindergarten, but since I carried it to and from kindergarten, and the case was stored separately until the end of each term, it's in good condition. I removed the previous name tag and ironed on new tape so you can write your name. The shoulder strap is removable. I will fold it up small for shipping. Pianica Pianica case Boy LEGO
