All the sets are hand painted, using top of the line nail polish for the best quality. The set will give you a perfect, non-damaging manicure within a few minutes for a small portion of the salon cost. Take a look at the Shapes and Sizing images where you can find the information on how to work out your size. Send me your size and we'll together, create the most satisfied, beautiful nail set you could ever wanted. We do not offer exchange due to hygiene reasons, but if you have any problems with our sets, just message us and we'll try our best to resolve it! Thank you for being the best part of LadyShopNails!
