A piece of unaged soap is just a piece of half-made soap, like red wine with insufficient age, green and moist. We have a small number of soap factories in the world that specialize in matured soap, have the only non-linear computer-controlled mature room in the country, and set the mature environmental parameters in accordance with the ancient Central Asian method with 20 years of experience. We insist that every bar of soap needs to be matured under strict control to nurture quality with time. Just like good wine, it needs to be matured in a suitable environment and time. To put it simply, we use time to distinguish our soap.
