Arm Foot Pro Arm Sling

I injured my arm and bought this on Amazon for about 3300 yen, but I haven't been able to use it, so I'm selling it.
It's brand new and unused, but I've thrown away the packaging, so I'll only be shipping the product itself.
Thank you in advance＾＾
I'm using the Amazon page where I purchased it.

I will ship via Click Post.
