This lead is meant for the breeds who use a choke chain, or collar or even a harness with a D ring.  It's a very strong lead, ALL breeds can use this lead.  It attaches to the ring of the collar easily.  I can also sew in a snap hook, for when you want to use the same lead with multiple dogs and want to change over quickly.  Go to the loop lead with snaphook page.
This lead is made of nylon unless you special request toy.  The nylon lead thickness is 3/16" with a length of about 3'. 
I do have colored crystals, they do not catch light as much as the clear, which I normally use.  If you want colored crystals instead of clear, ask me first if I have that color in stock before you order.
Easy to connect to a loop lead...poke small loop of lead through the ring on the choke collar, take the other end of the choke collar and poke the ring through the small loop of the lead, and cinch down.
