A Swiss-born key organizer who stacks multiple keys like a Swiss Army knife. Don't mess with your keys, carry them smartly. [Features of Keycabins] (1) Stack and store multiple keys and carry them quietly and compactly. (2) Keys will not collide with each other and make a harsh noise, so be quiet. The sound is quiet = it does not notify the surroundings when you go out or return home, so you can rest assured in terms of crime prevention. (3) Less action when using the key, reducing stress. If you have multiple keys, it is difficult to access the key you are looking for in one shot. A typical key case is an action of (1) opening the key case and (2) selecting a key, but since the position of the key is fixed in KEYCABINS, access to the key you are looking for is quick and smooth, and you can use it with one hand. (4) There is comfort when opening and closing the lock. This comfort is similar to how it is easier to tighten screws with a longer screwdriver than with a shorter screwdriver. [Features of aluminum type] Only the aluminum type has a different design on the front (with edges) and back (without edges) of the plate, and you can enjoy two patterns of design in one. Black, red, gray, and light blue are popular in that order.
