Our new Autism Awareness ID Necklace (military dog tag style) is made of nickel plated stainless steel and has hand applied enamel colors. The two sided design utilizes the familiar autism puzzle pattern on one side and the opposite side has a write on surface that can be used for "name" and "phone #" information. The CDC estimates that as many as 1 in 166 children are afflicted with ASD (Autism Spectrum Disorders). Each ID necklace comes with a 24" ball chain, red military dog tag silencer and is individually packaged.
