Frequently Asked Questions

Why do I only measure my thumb?

The thumb is the widest nail and reliably determines your hand size – so you can find the right category quickly and easily.

What sizes are available?

We currently offer Standard and Extra Large sizes. Both sets include multiple sizes, allowing you to customize your nails flexibly.

The standard set of 30 covers most hands – the largest thumbnail is up to 16 mm wide.

For particularly full nail beds, we recommend Extra Large so that everything fits perfectly.

Many designs are already available in both sizes, and we are gradually expanding our range to give you more and more choice.

What if I'm between two sizes?

If your measurement is just below or above 16 mm, you don't have to worry: a difference of 1-2 mm is not noticeable .

The important thing to remember is that a press-on that's too big won't fit perfectly, while a slightly smaller one will fit perfectly. Therefore, it's better to go a little smaller than too big – this way, your look will fit perfectly.
