I have tried several different sets of stirrers here on Amz but this set seems to be the best of the batch. My problem with others is the others did not stay centered when stirring. It is as if the magnet inside these stirrers was not centered making them rotate off axis which was OK at low speeds, but would spin out of control at high speeds. This set stays centered at all speeds. Great Set.

Perfect for stirring metallic inks and is just what I needed. If you do calligraphy and like using the metallic inks (I use Winsor and Newton) and don't like shaking and rolling the jar for a thousand years when the metals sink to the bottom , then this is the tool for you too.

They did the job. Having the rod to take out stirrers without emptying container beforehand or shoving hand in is nice. I really like the cross stir bar.

I loved this set it worked like a charm. It was a great deal to begin with. And when making poppers the retrieval stick worked like a charm!
