What it is
"Half-boiled soap" reproduces the glycerin-rich state that occurs during soap manufacturing. This face wash leaves your skin feeling fresh and naturally moisturized. Fragrance-free.
Ingredients
Water, glycerin, sorbitol, stearic acid, palmitic acid, propanediol, myristic acid, potassium hydroxide, lauric acid, sodium hydroxide, bentonite, calcium carbonate, charcoal
How to use
1. Take an appropriate amount (about 1-2cm) with your spatula. 2. Add cold or lukewarm water and create a good lather with a foaming net. 3. Roll the lather in circular motions over your skin to remove impurities. *Wash gently, massaging around the nostrils. *The charcoal ingredients in the gray portion have the effect of clearing pores. We recommend using the ingredients in order from top to bottom without mixing.

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.
