75 Topps Minis - observations and a question

[Kutcher55]

Hi, I just picked up a Topps mini starter set (~450 cards). Really psyched to finally build a modest version of this set. Anyway, a few observations and questions:

1. This must be one of the hardest sets out there to find centered. Between the narrowness of the side borders, combined with the penchant for diamond cuts, not to mention, the front and back seem to be rarely aligned. PSA 8+ really must earn it in this set. Can't even imagine how hard it must be to find a legit 10.

2. I have noticed that there seems to be a random card every 100 or so that is very much a different size from top to bottom. Some of them are noticeably shorter than standard while others are significantly longer. These are commons and there's next to no chance they have been tampered with IMO. Seems like a factory issue. I haven't built that many sets so I don't know if this issue is unique to the 75 minis, but it was surprising to see.

3. For people who own this set, I'm sure this question comes up a lot. How do you store them? Is there a box that works well? What about any customized binders that accommodate the smaller size? Any advice here is appreciated. Looking for a fun way to do this.
