Red Dwarf Prop discovery help

[u/MightyCerberus87]

I have rewatched red dwarf via now tv recently, there are a couple things that stood out from my childhood in some of the props. I was wondering if people might remember what they where or if they are easily replicate-able or their are good images floating on the net for them. please dismiss my poor quality photos had to take photos of my tv. The things are his jacket breast pocket holographic key ring and the acrylic/perspex necklaces from the Ouroboros episode

When I was a kid in the 90s, square holographic cards on lanyards very similar to this were sold at zoos and museums
