This listing is meant to accompany a full set of nails. This is meant to add an additional layer of gel top coat to protect a nail art design. Each set of nails comes with two layers of matte or shiny gel top coat already. 
 
This listing is for people who plan to reuse the press ons, time and time again. If you use the adhesive tab or adhesive tab + nail glue method, you can reuse them again and again with proper care.
 
For example, date night, concert or weekend nails (because the office doesn't allow creativity lol). 
 
** This is meant to add extra protection to the design on top, not provide extra strength, although there will be some. There is a listing for "Extra Hard Gel" which is for that purpose specifically.
