Hands-free crutches, black

This is a hands-free crutch that allows you to walk, but we recommend using it with just one crutch until you get used to it.
The retail price is 40,000 yen.

Unlike traditional crutches, your arms won't get tired.

Used only a few times indoors.

The intended use is the same as the device below.
Sorry for only posting one photo. It would be helpful if you could search for it.
