Our Press‑On Sizing Kits are designed to guarantee a perfect, comfortable fit. Each kit is specific to one shape and one length. Each shape and length fits differently, and your measurements will change depending on the style you choose. To ensure accuracy, each sizing kit contains one nail in every size for the selected shape and length only. You will receive a complete size run for the shape and length you select (e.g., Short Round, Medium Almond, Long Coffin). If you’d like to test a different shape or length, simply order an additional sizing kit for that option. By trying each size in the correct shape and length, you can confidently determine your exact fit before ordering your custom set, ensuring your nails sit flush, feel secure, and look professionally tailored to your hands.
