Don't know what sizes you need for your press on nails? The simplest way to figure this out is to order this sample pack which will have 10 blank nails of each size. All you need to do is firmly press the nails onto your natural nail to see which one is the best fit.
Write your sizes down in the comments section when you go to purchase your set of press on nails, from pinky to thumb for both your left and right hand.
Make sure to also write down your sizes somewhere safe, so you don't have to order another sample pack!
Please note: I am not responsible for incorrect sizing. So please make sure you size them up accurately :)
