This is the AKAIISHI "Beasoku-kin Maker 5-finger". It's a training tool to strengthen toe muscles and form the arch of the foot. I tried it 2 or 3 times, but it's been stored in the storage room since then, so I'm putting it up for sale. - Brand: AKAIISHI - Model Name: Beasoku-kin MAKER - How to use: Toe stretch and muscle strengthening - Color: Blue - Features: Training device for toes With instruction manual When shipping, I will take the product out of the box and fold the box to include it due to the size of the shipping box.
