Frame-shaped credit card case
A frame-type card case that allows you to insert and remove cards from both sides. It can store a total of six cards, and its special shape ensures that the cards will not fall out. It is a great item that can be used in a variety of situations, such as a minimalist wallet in the cashless era, as a credit card case, or as an IC card case.

Slide-type card insertion and removal
The card slot is a slide-type slot that allows you to insert and remove cards smoothly with a single action, while the shape of the slot is designed so that cards do not fall out when stored.
Pass holder/Suica case
It can be used as a case for all national transportation IC cards such as Suica, PASMO, TOICA, and ICOCA, as well as a pass case. You can pass through the ticket gate without taking out the card. You can also use your credit card while it is in the case when making contact payments.

Materials also used in aircraft
The case is made of solid duralumin, which is light and strong and is also used in aircraft bodies. The luxurious aluminum material makes this an elegant card case.

Redefining the card case for today and the future.
Nowadays, contactless touch payment and touch ticket gates are becoming mainstream, and the functions required for card cases have changed significantly. We have redefined the performance and shape to fit the future from the present, and created the "next-generation frame-type card case," which is lightweight and thin, with just the right amount of capacity to store all the cards you need and allows for smart touch payment.
Six-card slot
It can smoothly store a total of six cards, three on the front and three on the back. It is convenient to store frequently used IC cards and credit cards on the front, and insurance cards, driver's licenses, My Number cards, and other cards that you use less frequently but want to carry with you at all times on the inside.
The card case is designed to be easiest to insert and remove cards when it holds 6 cards. If you are storing 1-4 cards, add this placard or similar to the inside and use it to store a total of 5-6 cards.
*To get the most out of this product, we recommend using it with a total of 5 to 6 cards stored.






As a compact wallet
In order to pursue functionality and compactness, the body of the frame-type card case has been made ultra-lightweight and ultra-compact by removing all unnecessary material through cutting out the material to the bare minimum.






High hardness and ultra-lightweight material
The material used is "A2017", a solid duralumin used in aviation, space and racing parts. Among them, Furukawa Sky uses duralumin A2017S, which is said to be the highest quality. This lightweight and highly rigid card case protects your important cards from external impacts. It will not deform even with normal use. It weighs as light as two 500 yen coins.

A card case carved from a single sheet of aluminum
This product is machined from a single piece of duralumin, a highly reliable and reliable material, and finished with a seamless, stylish design. The elegant luster of the duralumin material and the simple, lean product design create a smart impression. Machined from a single piece, there are no seams, so the original strength of the material is not compromised.
Beautiful slim card case
The shape of the card case has been stripped of all unnecessary elements, making it beautiful from any angle and comfortable to hold. It is a seamless, slim card case made possible by being machined from aluminum.




You can attach AirTags and other accessories using the included strap. It can also be used to prevent your card case from getting lost. The strap is separate, so you can attach a variety of accessories.

[Prevents interference and poor contact between IC cards]
