What it is
This sheet mask contains our unique beauty ingredient, Cellul Nano Complex, which is made by nano-sizing carefully selected beauty ingredients using surfactant-free emulsification technology. Furthermore, we've carefully selected ingredients to perfectly complement the nonwoven fabric, which offers excellent adhesion and moisturizing power. This is an unprecedented mask containing nano-beauty serum that is hypoallergenic, highly penetrating, and adheres tightly to the skin. Its penetrating and moisturizing power allows the beauty ingredients to hydrate deep into the skin, instantly filling it with moisture.

After washing your face, tone your skin with toner and gently apply the face mask, focusing on the area around your eyes and mouth. Leave it on for 10-20 minutes, then remove the mask and allow the remaining serum to soak into your skin. The bottom of the film container can be cut off, allowing you to use any remaining serum on your décolleté or body after using the mask.

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.
I used it before going to bed and when I washed my face the next day, I noticed a difference in the texture of my skin, making it feel plumper. This might be great!
The soft sheet is soaked with beauty serum. It adheres well to the skin and is mild. After using the mask, your skin will feel moisturized, firm, and radiant.
I bought it because it has good ingredients and is reasonably priced, and I'm glad I did! It keeps my skin moisturized until morning. The only downside is that the packaging is a little difficult to open.
I only used one sheet. I bought it for less than 400 yen. The sheet is firm, the amount of liquid is generous, and it adheres well. However, for some reason, it stings only around my eyes. Maybe my skin was sensitive at the time. (No other areas sting.) I found the packaging interesting because it cuts from the bottom to avoid wasting the liquid.
The mask is very moisturizing and leaves your skin looking translucent once you've used it up.
