Highest quality top loaders

[Eric72]

Of all the ways to store single cards, my preferred method is the classic combination of a top loader and penny sleeve. I've used these for decades and purchased thousands of them along the way. From the '80s through 2020 or so, I very seldom experienced any issues.

For the past few years, though, I've noticed a problem. Ultra Pro top loaders have frequently been coming out of the pack curved. Seriously, when I look at the side/edge, the top loader resembles a banana. I initially thought it was just a bad batch or two; however, the problem seems to be ongoing. Again, this has been happening for a few years. I wind up tossing most (yes, more than 50%) of my new top loaders straight into the recycling bin. When I open a pack, there might be ten straight top loaders; the rest are curved.

I won't damage my cards by using defective supplies. I've had enough. It's time to find a new brand.

For those of you who still buy new top loaders, I'm looking for recommendations. What brand do you use?
