Press on nails

I will be selling press on nails. I will be following a nail size chart to display/sell some. This is my first time doing this. A way to measure your nails is using tape and measure your nails from side base to side base. I will be putting a instructions picture. Feel free to comment if you know your size. People measure their nails be millimeters in the measuring tape and I can tell what size is it. Thanks! Have a nice day!
