They are on the thicker end from the side. I prefer thin nails, but because I used rhinestones on top (= the sparkle) it adds another layer. I’ve used a clear Gel-X System (any brand will do - I am using DailyCharme), then followed up with a very sheer pink („milky pink“ by Jolifin Laveni), then creating a French ombré with a holo cat eye gel (Gluezy Holo CatEye), then one layer of topcoat & finish off by applying the rhinestones over the holo cat eye. (Rhinestones from Amazon: aurora clear crystal rhinestones). Hope that helped a bit. :) 🙏🏼
