Question about Phobya NanoGrease Extreme

Hello, in general I would say that it should not be older than two years. Provided, of course, it is in the tube and sealed. I recently threw away half a tube, and it was three years old. It took a lot of effort to get it out of the tube.

Thermal paste does not really have an expiry date, as long as it has not dried up, it can still be used years later.
