I'm a Professional Nail Technician. This set is a 12pc press on nails set. They are dual sided designed, the design is visible in and out of the nail with transparent glass type effect. They may seem a lil bumpy at first due to design but once you have them on, I'm sure you will love them.These nails are purely handmade and designed by me with love. These nails are reusable more or less depending upon the usage and care. A mini nail kit is included with the set.
