We just came across a large quantity of plain white poly shipping bags and are selling them in quantities of 25, 50 and 100.  Due to recent USPS increases, we are offering these at reasonable shipping charge - Orders will be shipped via USPS Ground Advantage. 

The brand name on these is PAC Worldwide, and these were made in Mexico

These are for the 9 x 12 inch size.  We also have these in the 10 x 13 inch size.  Check my other listings for those.  And we also have several lots of eBay-branded poly bags listed as well.  The eBay branded-poly bags are a little more expensive.

Long time and reputable eBay seller -- check out my feedback rating.

Very fast shipping - we ship within 24 hours of payment, often same day
