Lv4dogs, martingales have no clasps You can buy 1" martingales from any sighthound collar maker. You will find, however, that many designs require a 1.5" or 2" width. Of course, I recommend ClassicHound.com , but you can buy one inchers from a multitude of collar makers including Nancy B: community.webshots.com/user/nancybnj
and Greys and more Greys: www.collarsandstuff.com
