These bearings seem to be pretty good, especially for the money. Time will tell their overall quality. They feel smooth as you would expect from new and freshly packaged bearings. It will not leak or be damaged from the packaging. Minimal packaging, not sure if they are made in the UK or more likely made in China but the seals say UK. I'd be surprised if they were made in the UK at this price point, but so far I'm pleased. I will be buying more for future projects assuming they don't fail in the near future.
