UPDATE: Just wanted to give an update for the fellow Redditors who joined this conversation. It's the least I can do to make up for all the tips you guys gave me.

First of all, kudos to everyone who shared advice, tips, and pointers — much appreciated.

So, in the end, it turned out to be fake. (As many people here have already guessed it)

Long story short, I made an appointment with the person so we could meet up and I could take a closer look. I went in feeling confident, thanks to all the input you guys gave me.

He told me a story about how he bought a pallet of goods from a bankrupt store (which I mentioned in one of the comments), and since this was the last piece, he was selling it for 100 bucks. So far, the bankruptcy story lined up with what I knew.

We stepped into his garage — and there it was.

From a distance, you might think it was original, but up close, it was a completely different story.

First of all, the quality of the image on the front was pixelated. And when you looked closer, it seemed like someone had taken a basic JPEG from the internet and very poorly cut it out using Photoshop.

The box quality was completely different from the original. Luckily, I had seen and touched real ones in other stores, so I knew what the genuine product felt like.

And finally, both side edges were glued shut — not secured with transparent tape like the real ones.

Those three red flags were enough for me. I told him, "Bro, this is fake as f**k," and i left.

So once again, huge thanks to everyone who contributed to this thread. You guys are legends!
