I have to place this here, a terrific photo from @drifand that shows off a wide array of models in this type.
I think I had all of them or very close to it (not sure about the first white one). Definitely the Platinum was the best, more compact one.
To the OP @Pdunc67, the Yasutomo NIJI Grip 500 had a later iteration with better plastics
There’s also a nice fully transparent version by OHTO (for their own OHTO Griper line). My favourite is still the old blue one — they get a really nice patina when the brightness of the plastic fades a bit. Or maybe the plastic isn’t always the same and it only occurs in the softer plastic ones:
I believe the colours/pigments in plastic don’t behave all the same way when exposed to daylight over the years and maybe the way they are exposed affects that too.
Edit: I now realise that the plastic on that pic I posted is different, it is a mute, matte, variation of the more shiny one (the shiny one is possibly older). Which means I sold the one I should have kept! Cr*p.

Hey - just a clarification- that’s not my post. Another Reddit user who happens to be a pencil collector got stuck with a nearly identical screen name. What are the chances?
Gary had DMd me about it earlier, and after reading the post I was completely confused.
I looked at the date, then the screen name (assumed it was mine) and read the post again, thinking “has my hobby spawned a second personality that is posting (rather well written) posts now, or maybe I’ve had a stroke and don’t remember posting this?!!? OMG”.
Took me a few passes to realize what’s up.
Good luck guys. Sorry I couldn’t help
That is hilarious.
