Booklet Open Side Envelopes

Booklet envelopes are used for a wide variety of mailing and shipping functions. They come in standard size dimensions ranging from 4-3/4" x 6-1/2" to 10" x 13". They have side seam construction with a wallet flap which is located on the longer of the two dimensions. The term "open side" is sometimes used when referring to booklet envelopes. Common uses are for mailing pamphlets, brochures, sales literature, booklets, annual reports, and bulky materials that have some thickness to them.
