Soap, 80g

This additive-free soap contains silica, which has excellent beauty benefits, and the salt concentration of the foam when lathered is the same as normal saline (0.9%), making it safe for people with skin problems to use. It also contains no fragrances. Thanks to a special manufacturing process that barely traps water or air bubbles, the soap is extremely dense and difficult to dissolve, so it won't get mushy even in humid bathrooms and lasts a very long time.

Put soap into a foaming net, moisten it with a small amount of warm water, and lather well before use.
