Cost-effective additive-free soap, Neba Juku, Shirayuki no Uta, 180g x 2 bars, 4 sets

This item is brand new and unused.
Due to the tight dimensions, it will be shipped with simple packaging.
Specifically, it will be wrapped in plastic wrap, secured with packing tape, and placed in an envelope. Please be aware that there is a possibility of dents, chips, or even breakage during transit.
Although it is labeled for kitchen use, it is additive-free, so we primarily use it in the bath regardless of its intended purpose.
Each bar of soap weighs 180g, which is about twice the weight of a standard bar. This set includes two bars, so 4 sets would be equivalent to approximately 16 standard bars of soap.
4 sets is likely the maximum that can be sent via Yu-Packet Post, further improving the cost-effectiveness with included shipping.
It has a large, rugged feel similar to old-fashioned laundry soap, with a simple cellophane-only package. However, this simplicity makes it very cost-effective. It's not only one of the cheapest additive-free soaps available, but it also competes well in price with generally inexpensive soaps. The added benefit of being additive-free makes it highly recommended.
