This kit is great, the varnish can actually hold two weeks if done right (but see the regrowth of the nail, normal). The installation is a bit long but worth because it is just as long with classic varnish drying time. The color is pretty. Removal is a bit difficult but doable, provide a good lime remover with acetone and oil for nails and cuticles to feed them. I received the package in good condition, and no vial was empty. I regret that there is nothing scheduled for removal in the kit, and additional kit for removal is a little too expensive for me. Otherwise, great product. My nails were not damaged.
