This is a thirty piece key cover set with ten different colors to choose from! We sat right down and organized our keys immediately. Now we have them all color coded and know when we look at the key ring which key is the sets we want. I love this set because it was good quality and great assortment of colors and easy to put on the keys! We only had one broken one and that was opporator error, the key head was just too big for the ring. These fit most standard square and round key head, but do not fit the large bulbous ones or the really oblongated ones! Perfect!
