Beside Regiopost there is also the local
service for Friesland. Their designs look
very much like those of Regiopost,
maybe the same designers?
Merenpost is also for the same area,
but particulary delivers around the lakes
Others parts of Holland, or provinces
don't have a special regional service.
Mostly it is all about one city, but
the local services do work together
to make sure that your mail also
reaches your relatives in other places.
