Here is a cute and totally cool hack on how not to confuse your keys. This works perfectly when you have more than two sets of key for your home so you get to easier identify which among the keys you need to use. Color coding idea saves you time and effort finding the correct key, thumbs up!
I have seen these more than a couple of times in Pinterest. Aside that its functional, it also looks fun to create so I thought to do it as well.
I use my almost dry nail polishes, those that I am about to throw since I can no longer use them to paint my nails.
