(10 Pieces) PGN - 3/4 Inch (0.75) Precision Chrome Steel Bearing Balls G25

Have used these ball bearings to make many monkey fist key rings. The major advantage of this product is the substantial weight of the key ring which keeps the user from losing the key ring. When dropped it makes a sound even on a soft surface and is large enough to make it easy to find.

Well made, with no noticable imperfections.

I use them in physics classes as they are replicas of experiment by Galileo, Newton and others for classic mechanics.

Perfect. Just what I needed again. This is my second order of these.

Fast, well packaged and good quality

Ive definitely got balls of steel now!

Nothing but good things to say about PGN.

Prompt processing and delivery. These are very nice quality inexpensive bearings.

Worked perfectly used it to make monkey fist
