Pilot does not make a 0.5 refill for this pen. I've already asked. The refills
from the disposable range, I think, will not fit into this pen as the sizes are
different. That's why I asked the question if anyone else is interested in a 0.5
refill so as to hopefully coax Pilot into making them if enough people ask for
them and it becomes worthwhile for Pilot to make them. Personally, I think the
demand is there, it's just that either Pilot don't realise it or just don't want
to manufacture them for whatever reason! I think it's the latter.
