Product Identity

Quality Park 37682 is a box of 250 white booklet envelopes sized 12 x 9 inches and made from 28 lb stock. The open-side design on the long edge allows quick insertion of folded documents or booklets. Offices, schools and mailrooms use them for statements, catalogues and multi-page correspondence.

Seal Reliability

Wide gumming and deep flaps create a secure seal that resists accidental opening during transit. The 28 lb paper provides stiffness for machine feeding yet remains foldable for hand stuffing. Super white brightness improves legibility of printed addresses and barcodes.

Compatibility Check

Verify that your folder, inserter or printer accepts 12 x 9 inch open-side envelopes and handles 28 lb paper weight without jamming. Confirm the gummed flap works with your sealing equipment or moistener. Ensure storage space accommodates a 250-count box.

Questions about this item

Should I choose the 250-count box or a smaller pack for my mailing volume?

This listing is the 250-count box; if you need fewer envelopes you would have to look for a different SKU.

How does the 28 lb stock feel once it is loaded in a printer or mailing machine?

The 28 lb paper provides a firm, professional feel that feeds reliably through most office printers and inserters.

What does the open-side 12 x 9 format mean for inserting booklets or catalogues?

The opening runs along the 12-inch edge so wide booklets slide in without folding, and the deep flap with wide gumming seals securely.
