Our most common vinyl sleeve, opens on the Long side, with the pocket opening dropped a 1/4" below the top of the sleeve to facilitate easy document insertion. Sleeve sizing shown is for the largest document dimension that can be comfortably inserted (1/4" less than the Outside Dimensions (OD), both directions).
We manufacture these vinyl sleeves, basically any size, at our California location, some are in inventory, most are manufactured for your specific order, so you get exactly what you need.
Use the "Browse By" droplists to look for sleeve sizes at or a little larger than your document. A close sleeve size may have a better price and ship quicker.
