What do you guys use to hold your psa cases/card holders?

For the purpose of displaying the cards, what do yall use to hold them up?

I’ve seen PSA display stands for single cards and display cases for multiple cards. There are a fair few available on eBay. The few PSA cards I have are stacked on each other in my closet because I am not sure how I would like to display them. I’m more leaning towards putting them inside binder pages, I think the Ultra Pro 4-pocket pages for postcards fit PSA graded cards.
