This Star of David is precision carved out of non-magnetic, non reactive, bright finished, 100% 304 stainless steel. The dimensions are: 1" tall x 1" wide x 3/32" thick. The chain is the beaded "dog tag" type, 24" long, and also made of the same stainless steel. The simplicity and clean lines of the design makes it stand out above the crowded field of otherwise gaudy castings, which are irregularly shaped and finished. It's tough, because it has to be! If you could only hold it in your hand and feel how solid it really is...in more than one way, it's built to never let you down. The back is stamped with our Manufacturers "CAGE" Code: 3YWL0. Lifetime Warranty.
