Hi Mike,
Thanks for posting your question here. I am not entirely sure we offer the specific type of label you are referring to, but we do offer a few "Package Type" choices for USPS First Class Mail shipping and I believe the one called “Flat(Certified Only)” may be suitable for the shipment of your items.
If you click the “Get Shipping Label” button next to an item on the Transactions page within your Auctiva account and select “First Class” from the “Shipping Service” drop down menu, you should then be able to see these options in the “Package Type” drop down menu below.
For more information regarding the shipping label services we offer, I recommend reviewing the following section of our FAQ:
