What the other Larry said might be true, Ig, (it is in many other

The doubled price is about right for that. Do you want them to last

No, they are both ABEC-1.

I overlooked that they had Precision-Plus bearings for $11 apiece that
offer ABEC-3-like precision. But I do not think that anybody cares,
neither me nor the potential buyers.
