Priority Mail Envelope For Shipping Stamp Panes--Sturdy Enough?

A seller across the country told me that he would ship me a dozen stamp panes in a Priority Mail Flat Rate envelope with each pane separated by a piece of parchment paper. Would this envelope be sturdy enough to mail panes without them arriving bent or folded?

No. Those envelopes are flimsy. He needs to include cardboard stiffeners on both sides of the sheets.

Revenuecollector: Thank you for the info.

Are Priority Mail Flat Rate Envelopes processed with potentially heavy Priority Mail boxes to where the heavy boxes could crush the envelope?

A thoughtful seller (one who wants to avoid problems) will use adequate stiffeners in the packaging. You can always request that he/she do this.

It's not just the processing. Those envelopes could be bent, folded, spindled, and mutilated at any point along the delivery chain right up until it hits your door or PO box.

Those flat rate envelopes are meant primarily for documents, in which case if the envelope gets bent or folded, it's not a major concern; they're not intended to protect fragile items inside. If interior structure or stabilization is required, it's up to the shipper to add this, or use a flat rate box instead (more expensive).

There are no weight or thickness restrictions on Priority Envelopes that might increase the cost of shipment. So tell the seller to put some cardboard on each side of the sheets as suggested earlier.

I use recycled cardboard stiffeners in all that I ship. Green or cheap. One of the two. Or maybe both.
