Kids press-on sets can stay in place for about 7 days, while gel press-ons and gel polishes often advertise lasting up to 14 days with proper application and curing.
Magnetic gel polishes contain magnetic particles that are shaped with a magnet tool to create patterns; each nail is then cured under an LED lamp for about 60 seconds.
Advertised features often include quick-dry formulas, easy-glide or contoured brushes for even application, and some formulas that claim one-coat coverage.
Common palettes include metallic and iridescent shades available across light, medium, and dark tones.
Kits typically include many pre-sized adhesive nails (for example, 168-piece sets) and pre-glued stickers; application usually involves pressing each nail onto the natural nail for a few seconds.
