These are pumps from Akira Osaki Boutique. They are made of black velvet. The black satin ribbon is a lovely detail on these stylish pumps with a unique design. Perfect for a casual outing. They were custom-made and cost around 35,000 yen. The size is 23.5cm, and the heel is 8.5cm. I was looking forward to wearing them, but I injured my leg and can no longer wear heels, so I'm selling them. They are new and unused. They don't have the original box. However, I will ship them in a box from another brand or a box with some dents.
