Japanese Beauty Wraps the Heart


In Japan, there is a culture of carefully wrapping important things, such as furoshiki used for gifts, fukusas, and noshibukuro. We designed this clutch bag based on this traditional Japanese aesthetic of wrapping.
A single piece of leather is folded over beautifully like origami to wrap A3 size documents, tablet devices and laptops in A4 size. Elegantly removing important documents from this case will transform your presentation into something prestigious.

A4 size up to A3

A3 ドキュメントケース

Designed by an architect, the case's A4-size exterior allows A3 drawings, documents, and sheet music to be carried without creasing; an A4 clear file (w.220 h.310 mm) can also fit in the case.
There is no stitching around the perimeter, so there is no waste in size.

Attractive thick leather and minimalist form


leather used for this clutch bag is waxed, taut, and smooth to the touch. The leather used for this clutch bag is waxed and smooth to the touch, and the more you use it, the more beautifully and tastefully it changes.

Foschia: A foggy look Foschia)

Foschia" is the Italian word for "fog. The white wax gives the series a misty look.
The white powder is a wax called "bloom". The more you use the leather, the more the wax on the surface rubs off and permeates the leather, revealing the original transparent look of the leather, just like a morning mist clearing up.

シビラ エイジング

The leather has a firm impression with sufficient oil and a taut surface.
The shoulder is also a part of the leather that contains many rose scars, uneven colors, blood streaks, and wrinkles, allowing you to enjoy the expression that only natural leather can give you.
Since it contains sufficient oil and wax, no special maintenance is required.

*Please be careful not to transfer wax to dark-colored clothing.

SYRINX products are made of carefully selected materials. Please handle with care for long-lasting use.
Due to the finish that brings out the texture of the raw hides, there may be scratches, uneven coloring, stains, or wrinkles on the surface. Please note that due to the delicate surface, there is a possibility that slight scratches, press marks, and abrasions may be found during the manufacturing process.

White Wax Leather Care Instructions

No oil care is required for products just received. This leather contains sufficient oil inside the leather. Also, the white component on the surface is wax, which will penetrate into the leather and increase its waterproof effect as it is used. It also becomes transparent and shiny.

If the surface becomes dry after prolonged use, we recommend using a wax made from wax or oil to clean the surface.

In addition, it is very delicate to water and easily deformed by moisture, so we recommend the use of a fluorine-based waterproofing spray. (However, please use at your own risk.)

The following page explains how to spray with pictures.
Waterproof Spray Method

    Because tanned leather is dyed and finished, its surface is very delicate and easily scratched. However, if the leather is used with care, scratches and stains will gradually become a part of its texture. Daily wiping with a soft cloth and brushing are recommended, but the best maintenance is to use the leather and give it the proper amount of stimulation.

    Other points to note

    • Size may change slightly with use.
    • Color fading may occur. Please be careful not to combine with light-colored clothing.
    • Color and texture may vary depending on the lot and part.
    • Due to changes in temperature and other factors, oil and fat components may appear white on the surface. It can be removed by lightly rubbing the surface.
    • When storing the product for a long period of time, please air dry the product regularly with a soft cloth to prevent mold from forming.
    • The contents should not be left in place for long periods of time, but should be removed periodically to allow airflow inside.
    • The color of the product may look slightly different from the actual color of the product depending on the monitor environment.
