This is a key case for Suzuki smart keys (for sliding doors). It fits the key shape in the third image. Two-button versions are also listed separately. The color is stylish white x gold. (Black x gold is also listed separately.) The material is soft TPU, also used in smartphone soft cases. It absorbs impact from drops and protects your key. Button operation is possible with the case attached. If you would like a set of 2, I will create a dedicated listing, so please inquire through the question box. It's 1300 yen including shipping. Shipping will be via Yu-packet Post Mini. Free shipping.
