It helps mix the elements so they can be applied, like the ball in a paint spray can does

When I needed to replace a few missing balls in my bicycle, I had the option of driving to the local bicycle store and buying only what I needed, or paying a little more to buy this package of 500

New bikes will probably not have a lot of loose bearing balls

But the bicycle store sells only grade 300 stainless steel balls (not chrome steel), and a few extra would be handy

The balls are probably fine for other uses, but as paint Agitators in acrylic paints they cause rust.

hard round balls ... of course they're good, they're bearings ....

Installed balls on rear axle of my bicycle, already worked well for 500 miles,and there's no backlash or play, I guess it will last few thousands miles

Some of the best balls I've ever seen

nice balls.....

Nice balls!

While I don't have the right tools to measure them precisely, these appear to be very consistent balls

Good quality ball bearings individually packed by size

Great balls, came packaged well

Sturdy balls

Good value with what looks like a decent quality ball bearing

These appear to be good-quality bearing balls.

These were nice ball bearings to explore chainmaille captures
