This blue leather slave collar is 1-1/2" wide and is fitted with 3 thick Dee Rings in the front and sides.  The dee rings are 3/4" wide and welded. They are very thick at 4.7mm thickness.   

In the back is your choice of buckle. You have either a lockable buckle with padlock of your choice, or a standard buckle that does not lock. If you choose a lockable buckle then there will be no eyelets in the holes to fasten up. In order to accommodate the locking tongue, a special oval punch is used for making the holes since the leather needs to stretch of the locking tongue of the buckle. You may see the different padlocks available in my Metal Accessories Menu.

This leather slave collar is available in several colours and leathers. The main photo is showing the royal blue. The top leather is a royal blue leather upholstery hide that I get from the Napa Valley. It is a very vibrant smurf blue. This hide is bonded to a black "super soft hide" that is chrome-oil tanned for a struck-through dye penetration. It has a more pronounced pebble grain to it which gives in texture and a sumptuous feel against the skin!! Its very lush.  Feel free to read about all of the different leathers I use in me Leather Information page.  All in all the collar is about 10oz thick (3--3.2mm) The combination of hides makes for a very strong bonded collar.
