In Japan, women in their eighties and nineties still wash their own backs. Every day. Without strain.
They have used long woven cloths exactly like this one for hundreds of years, for exactly this reason. Not to chase unrealistic beauty standards. But to keep caring for themselves, without help.
The Toshi towel is built on that same tradition. Forty inches long, so both ends are always within reach no matter how stiff the shoulders. And when you want to wash somewhere easy to reach, like your arms or chest, you simply fold it over and use it like a normal washcloth. One towel for your whole body.
You spent your whole life taking care of yourself. This is simply how you keep doing it.
