Sorry OT.
All my stuff turns yellowish.
Even when they came in grey.
I don't smoke, none at home smoke.
I think it's the florescence light, I read somewhere that these things are like UV that decompose the plastic.
It's on like every night in my room.
I think it's some what true. Some stuff in my cupboard are still nice.
So I have swap their locations but I think it's a hassle to move them out/setup to use it and place them back in again.
Anyway, it rather too late as most been with the florescence light for over 10 years.
