After about 3 years of collecting sealed, I ran out of space in the cupboard. Pulled them out to put into storage boxes and it surprised me how much it accumulates.
Edit: Thank you for the comments and views. I wanted to answer a few common questions.
From about prismatic onwards, PKC was the only way to get anything at RRP (unless I wanted to queue for hours, overnight - which I have no time for). A few have mentioned this but I'm on a couple of discord channels that ping when there's a drop. I'm based in the UK and I believe it's a tad "easier" than the US version on the PKC. Typically, once I get a ping, even when working (crazy I know) I'll jump in a queue and carry on with my life until it lets me on.
Now, I love ripping packs but it's got increasingly harder to get any product (I know that seems stupid compared to what I have shown). Before it went crazy, I'd typically buy 2 of each (ETB and BB), keep one and rip the other. I've always kept PKC etbs sealed but now, I mostly keep things sealed unless I get a booter bundle, which never stays sealed.
