Available in three sizes: card size, wide size (suitable for pens), and A5. They allow for slim storage of belongings, fitting neatly into bags without bulk. A triangular slit on the left side allows for attachment with a keyring. The TPU material, also used in smartphone cases and shoe soles, is lightweight and easy to work with. While not fully waterproof, it offers protection against sudden rain.
