Key posted / Keys and locks

Key posted

Blind or not,when facing a string of keys,it is difficult to figure those keys actually fit to which locks.
Key posted,a kind of sticker which has different protruding letters to tell which key fit to which lock,
can solve the problem easily.That is to say,people just need to attach the Key posted onto the key,
when touching the Key posted,they can identify which keys fit to which lock.
