are these paints for freehand nail art?
If they are, i tend to buy mine for either my local art/stationery shop or the wincy little pots you tend to get with kids 'paint by numbers' from the toy shop! They are absolutely fine for nail art, dry quickly on the nail and once sealed/top coated last really well. Sometimes i need to water them down a bit, but this is a cheap way of getting a really good selection of colours.
hope this helps
