This set includes 24 pieces, along with a mini nail file, buffer, cuticle stick, adhesive tabs, nail glue, and alcohol wipe. Please be aware that colors may appear differently on screen due to lighting and color resolution. The lasting power of these press-on nails is dependent on your application and how much wear and tear your hands endure. For a weekend look, try using the adhesive tabs. With the help of nail glue, these nails can potentially last up to 14 days.
