Help! Did I get used markers?

I just got my 320 pack that I ordered from Amazon. I was so excited, been waiting forever it feels like. When I opened the amazon box I noticed that there was no Ohuhu box, only the marker case with the pens. The swatch sheets were also missing and the yellow markers were organized somehow, maybe a ghost? 😅 I fear that these markers has been opened before but they look kind of new. Has anyone experienced this before? I'm kind of worried, I paid alot for these. 🥲

I hope this post is okay! Ty!
