FOUND: small magnets premarked with north/south

Took me awhile! two messages ago I still hadn't found a source for small, not fancy, individual magnets that have the north south (or positive negative) sides marked, for those of us who can't make sense of compass instructions. Here is a source that looks very affordable: If anyone finds others, please do tell us.
