Sizing: the dog ears and goggles can fit a child or an adult, but the collar is mostly for a child or possibly an adult with a small neck (11 inch neck circumference or less). Dog tag lights up but needs a new battery. Since collar didn’t fit I just took dog tag off and safety pinned it to the zipper on my vest. Black film on lenses can be unscrewed and removed from goggles (I just wore as is). Great condition on all, only worn once for a few hours.
