I purchased a 3-piece bag set a few months ago, but I'm selling the key case since I don't use it. The following description was on ZOZOTOWN: ----- Width: 8cm x Height: 5.5cm x Depth: 3.5cm, Weight: 90g For keys from your home, office, or shop... Carry multiple keys "neatly and protected"! Compatible with smart keys of various car sizes. To prevent keys from accidentally falling out, it has a built-in key chain, so you can carry it with peace of mind◎ Comes with a carabiner hook that can be attached directly to your bag or belt. ----- The bag color is greige, but the key case is a dark brown color to match the color of the bag's handle. Although it is a new, unused item, please refrain from purchasing if you are sensitive to items stored at home.
