Why It Matters
Why Choosing The Right
Size Matters
A properly fitted press-on nail looks more natural, lasts longer, and feels more comfortable throughout wear.
Looks More Natural
A precise fit blends seamlessly with your natural nail for a flawless finish.
Better Retention
Well-sized nails adhere securely and stay in place for longer wear.
More Comfortable
No pinching or pressure — just a lightweight, barely-there feel.
Prevents Lifting
The right coverage keeps edges sealed and protects against daily wear.
How To Measure
Measure Your Nails In
3 Easy Steps
Tape Across
Apply a small piece of transparent tape across the widest part of your nail.
Mark The Edges
Mark both side edges of your nail with a pen where the nail bed ends.
Measure In MM
Remove the tape and measure the distance between marks in millimetres.
