I actually used this. It's a genuine professional product, so the retail price is about 40,000 yen. Size: 11 The photos might be a little difficult to see, but it's a gray tone. I've included a close-up of the fabric in the third photo. I'm selling it because I quit my job and no longer need it. It's a used item, so it's in good condition, but I'm offering it at a low price.
