Each sizing kit will have have nails with all sizes (0-11, or 0-10 for others depending on what length you pick).
There’s no need to return it just simply write down your measurements, take a picture, and send them via
Bujibratt- Instagram and Facebook or bujibrattco@gmail.com
For help with your measuring you can refer to the ‘Sizing and Measuring Guide’ in the footer menu.
HIGHLY recommend getting a sizing kit for each different length you want because sizes do vary among some of them!
