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  is  $5.90  ,15.00,and  12.00

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
