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 have ASD (Autism Spectrum Disorders). Each ID necklace comes with a 24" ball chain, red military dog tag silencer and is individually packaged.
