One Large 3" Inch Diameter Hardened Chrome Solid Steel Bearing Balls, Vigorous Precision Balls

I bought a 4.5" giant bearing as a gift and liked it so much, I bought one for myself. Both bearings arrived in perfect condition and rolled smoothly on a polished marble table. A year ago, I purchased a 5" bearing from a different company, and I returned it because it arrived out of round with dents.

Not a lot to be said about this one. It’s a smooth, shiny, heavy, 3 inch diameter ball. If you need this combination of things then this product is the way to go.

Perfect for making a bunch of monkey fists - at least that is what I have been using them for

I use this for a good hand and wrist workout. Perhaps not its intended use, but that's alright by me.Good size to grip in the hand while remaining maneuverable. I made sure to clean off the packing grease before trying to grip it (don't want this to slip out and fall on my foot). So far it's still remained rust free, despite openly sitting on my desk between uses. Pretty shiny - enough to act like a distorted mirror - though I could give it a good polish if I want to take my handprints off it.Since I'm not sticking it in a machine, I can't speak to its concentricity or any other important factor. Feels pretty round, though.

nice product

Needed some balls for marble run projects I am working on, these are perfect. Oh and they are shinyyyyyyy

I love these things. I haven't yet decided what kind of art project to make using them. But they are fun to just play with.

I bought for my artVery good quality and appearance
