I couldn't measure the chains exactly. but they are about 16" - 17" long with an extender 

These are new, but the cardboard hangers have some marks on them on both the front and back 

The retail price of each   is  $5.90 & 7.90

I am selling a number of jewelry items including more from Justice.  If you purchase more than one.please request an invoice so I can combine shipping for you
