Two envelopes arrived today with slit edges, and another was punctured due to the enclosure of an unprotected thick embellishment.
(Although it did have "Non-machinable" postage on it, it must have slipped through the sorting phase of processing.)
I had suggested in a previous message that we start using tabs of tape to reinforce our (four) envelope edges. Someone just sent me a good example of what I had in mind, whether it be clear tape, a little duct tape, packaging tape, etc. (Washi tape might not stick well enough.)
Sometimes a picture is worth a thousand words.
This may help to prevent damage during automatic sorting,
and hopefully loss of contents as well. Honi
