i see that i can just print it on regular printer paper. i'll just do that ,then apply to box/envelope and cover in packing tape so it's waterproof.

i figure padded envelopes for overs of 5 or less (each unit in it's own anti-static bag and bubble wrapped) and for bigger orders, boxes with foam inserts to separate the units. i already have a ton of cardboard and foam from other stuff, so it's no big to do that.
