I bought one with a larger content than the one I currently use. Although there is no problem in size, feeling of use, etc., I am worried about whether I can not bring it out because it involves removing during opening / closing. Since opening and closing and removal are not linked with what is currently used, I think that it will be improved as such.
It is a very convenient item. I bought it as a warehouse key storage. It is convenient because there is no worry about losing the key with the management of only the PIN number, I was surprised to make it quite sturdy.
