SIZING KIT DUO

Your Perfect Fit, Made Easy.

New here? Your Duo Kit is FREE when added to cart with your first nail set. We’ll ship it first so you can find your perfect fit before we begin your nails.

The Duo Kit includes two shapes, so you can try both at home and see what feels best. Perfect if you’re deciding between shapes or want options for future orders.

All nail sets can be created in any shape or length. While sizing is similar across shapes, trying both helps ensure the most comfortable, accurate fit.

Here’s how it works:

1. Add your nail set + Duo Kit to cart
2. We ship your sizing kit first
3. Try both shapes at home and note your sizes
4. Submit your sizes — then we begin your order

Nothing is finalized until you confirm your sizes, so you can make any adjustments after trying the kit on.

We’ll keep your sizes on file for all future orders, so you only need to size once.

One-time sizing, reusable forever, and trusted by thousands for a flawless fit every time.
