I noticed this mark on this cell recently and was wondering if anyone might know what could’ve caused it and if there is any way to try to correct it. I doubt it can be corrected but you never know. On the plus side in the 2nd photo it disappears when placed directly against a light source. Thank you in advance!

Wanted to put a feeler out. So hit me up if you’d potentially like to off load yours! Open or sealed is fine
