So, I have found some Pentium 2 stickers, which seems to be made of very thin but stiff metal. As in: can be bent, but then keeps that form:

The rest so far(all models), looks like soft 'paper' only:

- Question: does anyone know where to find some for other CPUs that are made of metal ?
Or what to search for on ebay ?

Or even domed badges or whathaveyou ?
As long as not just a regular flat/paper sticker....

Guess there were no 'DOS inside' thingies made...(?) 🤣
And win98 stickers are illegal to sell ?
