A couple of questions about Polaroid Cold Clip
I've came across a Polaroid Cold Clip on the cheap. I didn't even know about its existence and its purpose until now, but it sounds interesting.
I have a couple of questions:
1. It's surely an old accessory, so my question is: does it expire?
2. Is it worth/useful for new Polaroid Orignals 600 Color film?
Thanks in advance for your answers.
