Earth Cardboard Co., Ltd. (Headquarters: Ina-machi, Kitaadachi-gun, Saitama Prefecture; President & CEO: Toshimitsu Okuda), which manufactures and sells packaging materials mainly using cardboard, started selling a new product, "Craft Box for Wrapping 67x43x23," on Wednesday, March 25, 2026.
A new palm-sized, compact craft box is now available from Earth Cardboard. At first glance, it looks like a box made of thick paper, but it utilizes ultra-thin cardboard material (0.9mm thick).
Usually, craft boxes of this size use materials processed from thick paper called rigid boxes, and many have highly decorative designs. However, they can only be used in an already assembled state, which poses the problem of bulky luggage when bringing them into events.
To solve the above problem, this product was designed and developed focusing on the fact that the box can be assembled on-site during events. In the case of cardboard, since it is in a flat state before assembly, space-saving can be achieved by assembling it as needed.
When assembled, this product's outer dimensions are 80mm x 50mm x 25mm, and in its flat state before assembly, it is 175mm x 93mm x 1.8mm. Converted to volume ratio, this realizes a space saving of about 70%. It is an item that can respond to the earnest desire to reduce luggage even a little.

A cardboard box recommended for gift wrapping small items such as accessories and cosmetics.
The dimensions of the box are adjusted to fit in a standard size 3 envelope, and the depth of the box is designed to an outer dimension of 25mm to fit within the shipping standards of flea market apps (within 30mm). By putting the box in an envelope, product shipping is possible using delivery services such as non-standard size mail.
It can also be used for packing and shipping products listed and sold by individuals, such as on the flea market app "Mercari" and handmade work sales platforms "minne" and "Creema."
It is a convenient item not only for product shipping but also as a case to protect small items, or for in-store sales at exhibitions and spot sale events.
