It foams easily and is easy to wash and rinse off.
It has a mild scent and is a hand soap that moisturizes while washing. Strong-smelling hand soaps tend to clash with the scent of hand cream, so I'm glad I found this great product.
I had a good impression of Matsuyama Oil's cosmetics, so I tried this simple product too. It's also useful for washing off lipstick that has gotten off of masks in the sink.
I bought this as a refill. It's hard to find refill products, so I'm grateful for this. It's also very comfortable to use.
After using it, my skin doesn't feel too tight, which is just right. I've bought it many times.
