What is a Nail Passport?
Your Nail Passport records the width of every natural nail. It gives participating artists a consistent starting point when translating your hands into their own press-on sizing system.

Your draft stays privately on this device until the account-based Passport is ready.

Artists can map your measurements to their own size charts, reducing guesswork before you buy.
A Nail Passport improves communication and fit confidence; it is not a universal size guarantee. Every artist remains responsible for explaining how they convert measurements into their products.
