They are individually neatly packed in matching paper boxes and plastic bags. This is a good sign of quality. However, I have found that one of six bearings spins wobbly and vibrates at less than 2000 rpm and 40lb dynamic loads. I know it's not SKF, NSK, or TIMKEN, and $1 for a bearing means inexpensive. Be careful, you'd better buy enough bearings so you can change them when needed.
