The leather BDSM collars (collars) from this category are made of leather and are mainly worn within a BDSM role play . The collars are equipped with one or more rings to which chains, a name tag or cuffs can be attached. The collars can be used during a one-time role play , but are sometimes also worn for a longer period of time . In the latter case, there is often a steady relationship between Dom (the Dominant) and sub (the submissive). The collar is then worn to clarify this relationship.
