I do the same as klimczak and vrooomed. I prefer 3" D-ring binders and usually use Avery brand. But, like Dan, I'll use any binders I can get my hands on for my cards. Always D-ring, but not always a specific brand or thickness. If I am buying them myself, I use Avery 3" D-ring binders. I always use Ultra-Pro Platinum pages for my cards. Four inch spines get too heavy and anything less than 3 inches is only for a single player collection until that PC will not fit in there anymore. I'm not (really) a set collector, so I can't help much there. The sets that I do have are varied in what albums and how many sets per album.
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
