Monsenhor Envide Nefelibata sent me this paintbrush, #0000630, that has been used for "one stroke too many." And the special Nefelibata bar code. This all came in a clear plastic ziplock bag, which gave the postal people no difficulties at all. There's also a little sticker that says "This is not mailart. This is artbymail." Subtle but important difference? Thanks Monsenhor!
