I have purchased handcuff keys and holders over the years from HW, and they have the best prices and fast shipping. Yes, there are other police website you can get these same items but Handcuff Warehouse is where the tools of the trade is at! Awesome customer service from HW!
With this key holder I love using it due to the fact that it is always quick and easy for me to retrieve my keys. Only downside is that some keys that do not have a fairly open or circular hole in them for a key ring tend to get stuck in certain spots.
