This is almost perfect: the soap itself is not only benign to humans and the environment, but the individual packaging appears to be a paper napkin made from recycled paper, with a plain paper sticker holding it together and explaining the product (and full ingredient list!).
I bought 4 rounds of soap online, and they came packaged in a plain cardboard box, stuffed with newspaper. The only plastic was a single piece of packing tape, and the courier sticker. Everything else was either recyclable or home compostable. The box is reusable multiple times.
