The package is 22cm tall and 12.5cm wide. It will be shipped via standard mail (non-standard size). If you prefer tracking and anonymous shipping, we can accommodate you with Nekopos/Yu-packet for an additional 100 yen. Please comment before purchasing. The inner envelope is 21.5cm x 12cm, so it can be sent via standard postal mail within Japan. The design is likely to be well-received even if sent overseas!
