Northeastern Envelope Co. 3.75 x 8.75 Double Window Envelope 24 lb Blue Woodgrain Tint Box of 500

Envelope Dimensions and Quantity

This product is a box of 500 double-window envelopes measuring 3.75 by 8.75 inches. They are designed for businesses that mail invoices or statements where both a recipient and return address must show through the windows. The blue woodgrain tint on the inside adds opacity to protect document privacy during transit. Offices handling high-volume outbound mail will find the quantity practical for continuous use.

Installation and Common Issues

Using the envelopes requires inserting folded documents so that addresses align with the two window openings. The top window sits three-quarters by three and a half inches, positioned five-eighths from the left and two and five-eighths from the bottom. The bottom window measures one by four inches, placed five-eighths from the left and one-half from the bottom. Misaligned folds are the usual cause of addresses obscuring the window edges, which can delay automated sorting.

Critical Specification for Selection

The 24 lb White Wove paper weight determines whether this envelope suits your mailing equipment and postage class. Heavier stock feeds reliably in most desktop inserters but may exceed weight limits for standard letter rates when multiple pages are enclosed. The remoistening seal activates with water or a moistener; it does not offer a peel-and-stick alternative. Buyers who need a self-adhesive closure or a lighter paper grade for lower postage costs should choose a different product.
