This 'Ready to ship" set comes with 20-24 nails with no need to measure! They are ready to buy and wear rightaway. 
Each set comes with 1 glue, please buy extra glues and sticky tabs seperately. 
INSTRUCTIONS:
Push back cuticles
Buff away any dead skin from nail
Wipe over your nail with acetone/dehydration pad
Apply an even coat of glue over the nail
Press down with medium pressure to get rid of any air bubbles
TOP TIP! Make sure not to overlap the false nail on your skin as this will cause lifting!
