Is this Booster normal?

Hi, I almost check eBay every day for Pokémon cards, and I often look at booster packs as well, even though I would never actually buy single boosters on eBay.

Yesterday I came across a Crystal Guardians booster in this condition. Is it normal for the bottom to look like that? It looks pretty strange, and I’ve never seen anything like it before.

To me, it looks resealed, and what’s even more surprising is that 12 people have it on their watchlist.

I might be wrong though, and maybe this is actually normal or some kind of factory defect or something. Maybe you know more about it.

Just looks like its been stored poorly to me

I haven’t looked at these packs up close before. Reference images show the bottom crimps shouldn’t be cut out. It may just be a manufacturing defect since every crimp line is cut.
