Hello!
I've bought (from Kedo) two "overhauling kits", one for brake's master cylinder and the other for caliper's piston. In both kits, in addition to spares, I've found also a small round box containing a pink stuff: here's a photo.

I think that the pink matter is a kind of lubricant to be used when assembling parts: am I wrong?
Otherwise: what is it?
