What is the reason for giving a small card pouch a 3cm width?
Small, palm-sized pouches are often made light and flat. It makes one curious why it was given a three-dimensional width despite its small size, and what items can actually fit inside.
It was designed with three-dimensional space so that it does not stay just a wallet for flat cards and cash, but can also hold wireless earphones that have thickness.
HIKER WORKSHOP's Micro Kitsune pouch weighs only 12g, but its shape is not a flat plane[1]. It has a three-dimensional structure with a width of 11cm, length of 7cm, and depth of 3cm[2][3]. Unlike ordinary card wallets that only fit thin cards and banknotes, it fits even AirPods, which have thickness, all at once[4].
The opening length is 7.5cm[5][6]. It is a width that allows you to insert your fingers and pick up small items touching the bottom without difficulty. A flexible loop is attached to the side, allowing you to hang a carabiner[7]. If you hang it on a backpack strap or pant loop, you can immediately take out necessary belongings without stopping your stride[8].
hmmm, it is a practical design that maintains a lightweight of 12g while not giving up three-dimensional volume.



It has not yet been confirmed whether there is a separate divider inside the pouch to store cards and AirPods separately.
