求翻译：卖方应在每件包装上，用不褪色油墨清楚地标刷件号、尺码、毛重、净重，“此端向上”、“小心轻放”“切勿受潮”等字样是什么意思？

Seller shall, on each package with indelible ink clearly marked brush part number, size, gross weight, the words "This side up", "Handle with care" and "KEEP AWAY"

The seller should be in every part on the packaging, with no fading inks clearly marked brush part number, size, gross weight, net weight, and "This End Up" and "Handle with care" and "never gets wet, the words."

The seller should on each packing, brush the parts number, the measurement, the gross weight, the net weight with the non-fading printing ink clear terrestrial reference, “this end is upward” “carefully, puts lightly” “is sure not to be affected with damp” and so on the inscriptions

The seller should be on every package, with permanent ink clear landmarks, brush, size, gross weight, net weight, "This Side Up", "handle with care", "keep dry" words
