Ultra Pro Premium Pro-Binder (12 Pocket)

Hi everyone, I recently purchased an “Ultra Pro Premium Pro-Binder” (12 Pocket) to store some low-mid price range cards. Here’s a picture:

I’ve used about 450 of the slots available, and was starting to worry that it was becoming too bulky, and was concerned some of the inner cards would bend (especially long term).

This is probably just me being paranoid, but thought I’d ask if anyone here has had experience with this binder when full (positive or negative)? I can post some pictures if needed later on too.

Thank you all for the help :blush:
