This Lockable BDSM Collar with 3/4" Dee Ring is 1" wide and is fitted with a 4.7mm thick welded Dee Ring in the front with a leather strap holding it into place with a set of double capped rivets.  

In the back of the BDSM Collar there is a choice of buckles. You may have the Standard non-locking buckle, or the Lockable Buckle w/Padlock. I use eyelets in the holes for the Standard Buckle option and oval punched holes for the lockable buckle w/padlock option. The leather needs to stretch over the special shaped locking tongue of the buckle, so no eyelets can be used.   You can choose which padlock you would like to have with your bondage collar if you choose the lockable w/padlock option. If you don’t choose, I will choose a padlock for you. You can see all of the available padlocks in my Metal Accessories Menu.

There are 25+ different leather choices to have this collar made in. Black Latigo is shown in the main photo and is a thick leather with a smooth and supple grain to it. My line of Latigo Leather is chrome veg retanned using U.S. heavy native steer hides which gives a perfect blend of greases and waxes. Chrome tannage lends a touch of strength while the veg tannage excels at adding excellent firmness and durability.  I bevel and burnish all of the edges on the collar so they are rounded and very comfortable and do not chafe the skin.  The Latigo hides range from 9/10oz thick.  Please feel free to read a FULL description of all available leathers in my Leather Information page.
