There some people not sure about how a key holder work,
so I decided to post a short instruction for you all ^^
First, take out your key holder
Pull out the key chain, attach your keys (as shown in the photo)
(ps: The cloth button is movable..)
Then, pull up the string
Jeng jeng jeng~
DONE!
Your key is now safely 'hide' inside your key holder
