This is the nail sticker that I use to create my press-on nail designs.
Each sticker measures approximately 8 cm × 10 cm (3.15″ × 3.94″) and comes in a plastic packaging bag.

The stickers have adhesive on the back and can be applied directly onto natural nails, nail polish, or gel.
For longer wear time, I recommend applying a thin layer of top coat gel or clear polish and curing or drying it after application.
