Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
It's a four-sided block, and you use it in the order of the numbers written on the surface. It looks cute and I found it easy to use. By using it, I was able to smooth the surface of my nails and shape them. It looks like I'm aiming for beautiful nails!
If you polish your nails in order with different buffers (1-4), they will become shiny. I bought this to try harder at nail care.
I've only ever used this product so I'm not sure, but I have no problems using it!
It's a shame that it's so inflexible...
I've been using a nail file, but I bought this because I can use it to file the surface of my nails as well. It's very convenient.
