Slingback mules with a glamorous jewel motif. - Design: Slingback mules with jewel motif - Color: Black - Size: 375 - Material: Synthetic leather - Embellishment: Crystal jewels Retail price: ¥41,800 brand: prank project A sister brand of Maison Special. I've worn them a few times, so a few jewels have come off, but it's not very noticeable! They go well with both sweatshirts and slacks, so they're versatile. The mule straps hook around the heel, making them easy to put on and take off!
