BLAX RUBY 24.0cm I bought these used and wore them about twice. They no longer fit, so I'm hoping someone else can use them! Please check the photos for scratches, signs of wear, and dirt. They tighten with a twisting motion and loosen smoothly when pulled, making them easy to put on and take off. I packed them with care, but I have a cat, so please refrain from purchasing if you are concerned. (´；ω；｀)
