NOTE: The satin lining will be revealed when the collar is adjusted LARGER. At its smallest adjustment the collar will not reveal the satin lining. The small martingale loop is not satin lined because it needs to rotate freely to operate correctly. OUR MARTINGALE COLLAR SIZING CHART IS LOCATED IN THE PHOTOS Our 2” wide martingale collars are satin lined for comfort and constructed using heavy duty webbing, heavy duty metal hardware and your choice of styles including martingale, buckle martingale fitted with plastic or metal (aluminum) buckle or a chain martingale. All seams are sewn using a triple box stitch for strength and durability. The breaking strength of the martingale styles is as follows: Martingale: 250lbs Regular (Plastic) Buckle Martingale: 175lbs Metal Buckle Martingale: 500 lbs Chain Martingale: 350 lbs We do not recommend walking a dog on lead weighing greater than 100lbs on a REGULAR Buckle Martingale. If you are using it for neck ware only it will be perfectly fine If you are interested in BUCKLE dog collars you can see them in our shop HERE: https://www.etsy.com/shop/thedecadentdog?ref=shop-header-name&listing_id=1379733059&from_page=listing§ion_id=26875072 Need a custom size...no problem...please message me.
