Review on 🖨 Enhance Printer Performance with JGAurora LM08LUU LM8LUU Printer Bearings by Ryan Hampton

They came in a thick ziplock plastic bag, then this bag was in another sealed plastic bag, and for good reason. They are completely saturated with fat, the inner bag is half full. And it's that gritty, low-quality stuff that you probably want to clean and replace anyway. The bearings are loud as you would expect at this price point. But if you're just trying to put together a cheap motion system (3DP) it will work as intended. They move smoothly.
