These spiked panties are made of genuine, two-layer smooth leather. Inside, there is a spiked liner part in the genital area, which can be easily removed with snaps, allowing the panties to be used without it. The straps on both sides of the hips and on the back of the buttocks are adjustable and can be fastened with a lockable buckle, to which we also include locks – the price includes these. Every part of the panties consists of two layers of softer leather. The straps as well. Please provide your hip and groin sizes! As shown in the attached photo: We measure from the front hip backwards between the legs to the back hip.
