How To Pick The Correct Size

1. Check the sidewalls first
   Choose a dual form that fully covers the nail from sidewall to sidewall without pressing into the skin. If it’s too tight, size up.

2. Avoid gaps
   The form should sit flush against the nail. Gaps can cause lifting or uneven product application.

3. Size up if unsure
   If you’re between sizes, always choose the larger one—you can gently file the edges for a perfect fit after curing.

4. Test before applying product
   Place the form on the natural nail without product to ensure it sits comfortably and evenly.

5. Match the cuticle curve
   The cuticle area of the form should align naturally with your nail’s shape for a seamless finish.

6. Check the length and apex
   Make sure the form gives you the desired length and structure before applying your gel or poly gel.

Pro tip: Every nail can be a different size—don’t assume one form will fit all fingers.
