12" Polypropylene Outer Record Sleeves

Does the job - nice product!

The strongest type available which will stand up to being handled far better and keep the sleeves within better protected from corner dings. Slight annoyances are they are very slippy when you try to grab a few of them, like ice cubes,😋. And they can be awkward in the shelves and topple over if you don't angle them sharp enough to not bound over.
