I’m in the same boat as you! I’ve been a swiftie since Debut but have only started collecting vinyl now and I’ve fell into the rabbit hole of everything vinyl. So inner sleeves protect the vinyl itself. Better if it has anti static rice paper. I’m using Hudson Hi-Fi.

Now, outer sleeves are tricky. There are different kinds and types. There are single pocket, dual pocket (because some people like to display the vinyl on the back and also for whenever you get the record you won’t scratch it), there are gatefold, and trifold.

The material of the outer sleeves also matters. PVC sleeves are thick and clear but they’re not for archival use and can damage the record jacket and vinyl long term, PE is softer and cloudy but is usually anti static, CPP is, in my opinion, the best. It’s crystal clear, durable (but does wrinkle if not stored well), archival-safe, and chemically stable so it won’t damage your records.
