IMPORTANT * Apres is a relatively young company and they are still improving their products. The first version of their nail tips has the size number on them. The second version has their Apres logo on their nail tips. However, their newest version is clear/blank. This is the reason why you may see some little differences if you ordered several times. * The significance of Apres nail tips is perfectly thick. They are not too thick (It will look unnatural on your hand) - not too thin (too fragile, so need to apply powder on it).* There is no Tips size 00 in their Box.
