This is a replacement, please please put the nail size and the order number that the replacement nail is from. I do a lot of sets this might help me remember the color and particulars of the set you ordered. Also send a picture of the set to firstname.lastname@example.org. Again this is to help replace the nail to get it as close to the set you bought as possible. No guarantee is made that the color will match exactly because I may have mixed a custom color.
