Waxed leather wrapped in mist
Only Misty Chocolate is the old specification, so it is being sold at the old price of 33,000 yen (while stocks last).
Japanese beauty that embraces the soul
In Japan, there is a culture of carefully wrapping important items with wrapping cloths, fukusa, noshi bags, etc. used for gifts. This document case was designed based on the traditional Japanese aesthetic of "wrapping."
Elegantly removing your important documents from this case will add elegance to your presentation.
A3 without folding
With an outer shape the same as A4 size, you can carry A3 drawings, documents, and sheet music without folding them. It can also hold A4 size clear files (w.220 h.310 mm).
There are also no stitches around the outside circumference, so there is no wasted size.
Can also hold a laptop and small items
It's not just for documents. It fits A4 size laptops and tablets (within 30.5cm width, 21.5cm depth, and 2cm height). It can also store small items such as pen cases and business card holders.
Everything is gently wrapped up, so you can head to your meeting with ease with just this case.
Wrapping important documents in the finest materials
The leather is traditional Italian Vachetta leather. It is smooth to the touch, and the more you use it, the deeper the color and luster will become. It is made from a single piece of leather measuring approximately 71 x 43 cm, allowing you to enjoy the texture of the material. The polished edge lines create a minimalist form that flows seamlessly.
Please note that due to the large size of the leather, natural marks (tiger stripes, blood vessels, small scratches, stains) cannot be avoided.
Beautiful details
The ends are lined, dyed and polished.
Origins
Foschia means "mist" in Italian. It is characterized by its appearance, covered in white wax like a morning mist. As you use it, the wax penetrates the leather, revealing a translucent finish.
Tanning and Manufacturing
Made from bovine shoulder leather from Northern Europe. After vegetable tanning, the surface is lightly buffed (polished) and then treated with white wax. The tanning agent used is derived from the tara pod, a legume native to South America. Although rare, it produces the lightest color among vegetable tannins and offers excellent lightfastness. This allows for a whiter tan than usual, achieving beautiful light colors using only dyes, without pigments. Natural marks may also be visible.
LWG (Leather Working Group) environmental certification Gold rated.
Maintenance
As the wax gradually penetrates, it develops an elegant and natural luster. Furthermore, it contains an appropriate amount of oil, so oil care is unnecessary unless scratches or dryness are a concern. For more details, please refer to here.
Light colors are delicate on the surface and prone to visible stains and scratches, so careful handling is required.

Keychain. I have purchased business card holders, pen cases, wallets, etc. I like the quality of all of them. The designs are also innovative and fun to use. The document case did not have a button backing, so I inquired about it, and I was very surprised by how quickly they responded. It made me feel that they are very dedicated to creating their products. I will continue to use them carefully.
