This is one kimono tatou-shi, a special, kimono storage wrapper, sometimes also called tatoshi or tatogami. These are hard to find, so, when I run out, it is very unlikely that I shall get more.
Fold your kimono the traditional way and lay it inside the wrapper, then tie it closed. Kimonos should not be hung on standard coat hangers, as this puts too much strain on the seams and fabric, due to their shape and most being hand sewn
It is made from acid free, thick, Japanese paper, specially designed to contain one (or more, if you wish) Japanese kimono. It has ties i outside to hold it closed. The Japanese use these to store and protect their kimonos and obi.
It will be sent to you folded, so expect fold creases
A touch of lavender or cedarwood essential oil on the outside of the wrapper (or stored on a tissue beside it) will also help keep moths away. Do not let oil come into contact with the actual obi fabric. A pouch of dried lavender works too
The Japanese take great pains to store their traditional garments with the utmost care, which is why they stay in such exceptional condition
