eBay

Hi, I have recently shipped some orders using eBay standard envelope. My shipments are still showing as "label created" a day after sending my packages to the post office. If the envelope thickness is 0.5in at some points will it get rejected by USPS...

So I recently shipped a card using a bubble mailer with eBay standard envelope. Prior to shipping, I had no idea they were not allowed. What are issues going to arise and how can I resolve them?
