The neoprene shell surrounds the retainer case and secures it with a zipper. As if that’s not enough, Retain-It includes a loop with a sturdy metal carabiner clip, for attaching your retainer case to a belt loop or a bag. That retainer isn’t going anywhere when it’s secured in a Retain-It case!
Retain-It includes a standard sized clear hard plastic retainer case, a neoprene zippered holder, and a metal carabiner.
