Anyone store sets in penny sleeves?

I keep all my cards in Card Saver 1's and 2's and store them in old library card files (the ones that used to hold the index cards for every book in the library in the pre-digital age) that I have found at various antique sales over the years. They are the perfect size and make it easy to look at - just pull out a drawer and flip through! I find binders to be unwieldy and for a collection of my size they would take up too much space.

I use penny slaves for almost everything. I collect low grade, and so honestly do not care much about condition, but I have never had a card damaged in a penny sleeve. I don't think you really need a top loader to protect from handling wear, unless you're prone to dropping cards or have kids in the house

I much prefer the ability to read the backs easily. Also, finding a new card needed for a master set that I hadn't identified before and having to move 500 cards one slot over in a binder got really annoying.
