Anal jewellery is a specific erotic aid that serves to tease and at the same time decorate your ass. They usually have the shape of a classic pin with a rounded head and a wider base. This foot can be set with a cut stone / crystal (or its imitation), or supplemented with another decorative element. Also, for practical (durability, strength, slip resistance, …) and aesthetic reasons, these tools are made of stainless steel.
