Additive-free Shabondama Snowl Soap 180g x 6

This soap is additive-free and suitable for laundry. Shirayuki no Uta is also additive-free and suitable for kitchen use. Both are 180 grams per bar, so they seem similar.
Shirayuki no Uta tends to lose oil relatively easily, and perhaps because of that, it doesn't seem to get used up quickly. However, for Shabondama Snow, other users' reviews often mention good lathering and quick depletion.
Many people use both for bathing, and I also use Shirayuki no Uta for bathing.
Afterward, I used it in the bath, but I felt the lathering was poor.
This is my impression as a bath soap. Since it's originally a laundry soap, it makes sense that good lathering could cause foam to overflow from the washing machine.
Since it's additive-free, I think it can basically be used for anything, but in terms of suitability, while it's cost-effective, its lathering makes it a bit questionable as a bath soap. Also, regarding allergies, just like with food and metals, there can be compatibility issues with oils even if they are additive-free.
Since the price of Shirayuki no Uta has increased, this one is more cost-effective.
Due to the tight packaging size, simple packaging will be used, and please be aware that there is a possibility of cracking, chipping, or denting.
