Miracle Giants Dome-kun Pencil Case Gakken - Not for Sale (1988) Size: Approximately 22cm long x 4cm wide x 2cm high New, unused item, but it is a very old used item from over 40 years ago. Therefore, there is some rust, dirt, and discoloration due to aging. Due to long-term home storage, I would like to sell it to someone who understands and will cherish it. ★ Please also see my profile.
