Edit: it is AI generated, completely missed the genAI tag on the Adobe Stock website, and [4] is not a ton like I thought, it's 307kg

It's listed on Adobe Stock photos[1]

I did find other similar photos[2][3] so it looks like it's an actual thing that exists. Actually found a listing for a 1 metric ton roll of it[4].
