When it comes envelope sizes, the 10 X 13 booklet envelope is a giant. These envelopes are designed to carry stacks of documents that are too important to be folded such as agreement copies, certificates, large marketing photographs, and more. This 10 X 13 white booklet envelope is crafted from high quality 28lb paper. This makes the envelope much more resilient than standard 24lb paper envelopes. Instead of standard remoistening seals, these come with peel & seal closure system. The envelope has a booklet-style design, which means the flap is located on the longer end. This envelope has no windows and it has a rectangular flap.
Customers who want personalized envelopes can have their company’s black and white logos pre-printed on these envelopes for free. These envelopes measure 10 X 13 inches and they come with a flat space of 9.75 x 12.25 inches. This is more than good enough to fit a thick stack of unfolded A4 documents.
