9x12 Clasp Envelopes for Documents

Quality Park 37890 envelopes measure 9 by 12 inches and come in a box of 100. They are made from 28 lb brown kraft stock for filing, storing or mailing flat items such as contracts and photos.

Double-Prong Metal Clasps and Gummed Flaps

Each envelope has a double-prong metal clasp with reinforced eyelets plus a deeply gummed flap that seals when moistened. The clasp allows repeated opening and closing while the gummed strip provides a secure seal for posting.

28 lb Kraft Weight Limits Bulk Mailing

The 28 lb paper gives tear resistance for everyday handling but adds weight when many envelopes are mailed together. Buyers sending large volumes should check postal weight limits, and those needing self-seal or peel-and-seal closures will need a different product.

Questions about this item

How thick a stack of paper can the metal clasp on these 9 x 12 envelopes actually hold?

The double-prong metal clasp with reinforced eyelets is designed for heavyweight 28 lb kraft stock, securing bulky contracts, catalogs or registration packets without tearing the envelope.

Will a box of 100 envelopes measuring 12.12 x 11 x 3.87 inches fit on a standard office shelf?

The carton dimensions are 12.12 inches wide, 11 inches deep and 3.87 inches high, so it fits most standard shelving bays and drawer units used for office supplies.

What is the correct way to moisten the gummed flap so the seal holds during mailing?

Use an envelope moistener or a damp sponge to apply an even layer of moisture across the full length of the adhesive strip; pressing firmly for several seconds creates a strong, sanitary seal.
