Approximately 6.5 cm. In the third photo, the colors are slightly different. The right side is a light sky blue, and the left side is a light green. There is no box. It has been in a Mizuya chest for a long time, so it has some minor scratches. There are a few small stains from being placed. I will wrap it in cushioning material and ship it via Yu-Packet Mini. Please refrain from purchasing if you are sensitive to imperfections. Returns and various complaints are not accepted. m(__)m ☆Price is not negotiable.
