This day collar is the perfect millimeter for day wear. I like to wear this collar a little longer, more like a necklace. The end caps are sterling silver plated. The heart lock is a working lock that comes with two keys._____________________Please Read Information Below_____________________***This item is custom made for you to your specifications.
