Whitening on back top center

Where do these whitening specks on the back top center come from? Is this from PSA casing the card? I’ve seen it on multiple PSA 10 1st edition base cards.

Here’s one example from the upcoming PWCC auction: Mewtwo

Never used PWCC before to look at cards, how the hell do you open up the image of the card? when i click the photo and link of the listing it brings me back to the same page. Sorry noob here.

Normally those center top chips happen while pulling cards out of binder sheets or tight fitting sleeves (normally there’ll be more specs than that). Or during the manufacturing sheet cutting process.
