Review on Adecco LLC Nail Swatch Sticks: Nail Polish Display Chart Practice Tool - 100 Pack - Ideal for Salon, Gel Polish, False Nails, and Nail Art Tips by Chris Pinkston

I like these. I could finally see that my collection (which is growing all the time) has a few duplicate polishes. I have 2 cons. Make no mistake! If you make a mistake, you might as well throw the stick away. Acetone will corrode them. I made a mistake when marking with a marker. I used acetone to wipe it off. I still use a stick because it's cheap and you can still read from the other side. But now it looks very scratched.2. It comes with a bolt and nut used to hold all the sticks together. It's not a very practical way to do this. If you add another color to your collection (and you have mild OCD), you'll have to take them all off and put them back on. Even when it's full, the little nut doesn't want to stay put, and then you end up with a pile of test sticks on the floor. I recommend using short chains and clasps to secure them, or some people use tie rings. And 2 tips: 1. Clean them with alcohol before marking or polishing. Mine were a bit dusty. Probably from production or storage. In any case, it is better that they are clean before swatching.2. Paint the bottom (concave side) of the "nail". This way it won't chip and you don't need to apply a top coat, the plastic acts as a top coat.
