Source for metal balls

[Sharon Brooks]

I recently obtained an Instrumentarium OP-100 and hope to start doing some
implant imaging soon. The guidebook suggests using a metal ball on the bite
registration to help in checking magnification and also in verifying that
the cut is in the appropriate location. I inherited many things from Al
Richards when he retired many years ago, but the only metal balls I can
find in the collection seem too large to me and also do not have a size
designation.

Can anyone direct me to a source for metal balls that I can buy in a
variety of sizes for a variety of imaging projects?

Thanks.
