Anyone know what these are?

Firm plastic (like tupperware, not completely hard), each with a small hole that goes roughly 50% through.

Should I be capping garden canes, modelling DNA, or what??? They were with my Dad's tools.

Beads to make an abacus or something..

See original post "each with a small hole that goes roughly 50% through". I am not sure they would slide along the abacus bar like that.

I have seen similar large red ones on brass-encased thermometers used for taking the temperature of concrete but that is unlikely to be correct.

Not enough colours for an abacus, you want at least units, tens, hundreds and thousands .
