Marked NSFW because of the stains.

I recently noticed a very tiny, hard, raised bump in the silicone of my Saalt disc. I've been using it for years and now and don't recall it being there, but the more I look at it, the more I'm doubting myself...

Is it safe to use? A sign of degrading? Or is it part of the Saalt disc that I've never noticed?

I appreciate any feedback!
