Product identity

Business Source 4648 catalog envelopes measure 9 by 12 inches and come in boxes of 100. The 28 lb white wove stock provides a professional feel for everyday mailing tasks. The press-and-seal flap closes on contact without any moistening required. Office teams and home offices can seal large batches quickly and cleanly.

Sustained use behaviour

Repeated sealing cycles maintain consistent adhesion because the adhesive activates on pressure alone. The 28 lb paper resists tearing during frequent handling and stuffing. No moisture means envelopes stay flat and do not curl in humid conditions. Buyers who need window styles or security tinting will not find those features here.
