These leather collars are made to order, and made to measure. We ask you to provide your measurement at the checkout. We tend to add a little space to make it comfortable but if you prefer a tight fit (or have added a little extra already) please let us know. The collars are locking collars, with coordinating cute pink padlock. This is supplied with a key. The collar comes with a beautiful metal chain, and matching leather handle. All gift wrapped beautifully in a pink box, and decorated with a satin ribbon.
