Personal Post Office Scale

The Personal Post Office Scale (aka the MP 4000) is a beautifully dowdy appliance that lets the layperson emulate both Lady Justice and postal worker. Attach the alligator clip to the item to be mailed, hold the scale aloft by its ring, wait for the pointer to steady, and you’re done. The scale weighs up to four ounces of postal matter and comes with an impressive-looking, fold-out “up-to-date rate card” and vinyl case. Only $4.75 plus shipping from Metal Products Engineering, Inc. The case reminds me of the “I.D. wallets” of my espionage-filled youth. (Secret agents always carry I.D., right?)

My only connection to Metal Products Engineering is that of a happy customer.
