Hi, Whatsyourburn. If you are looking for a poly mailer with printing on it, I was also looking around and came across a company named Derisory Designs. I have never used them so I cannot vouch for the quality. I got a custom quote and its not too high, I believe the minimum is 100, which is what I was looking for since Im trying to do special editions with matching packaging. PS. Im not sure if you are talking about the inner clear packaging, if so you can consider a clear backing along with vinyl sticker, and just buy 1k+ clear bags and use them to customize it. Depends on your budget and quantity needed. But anyhow good luck!
