Common questions
Can these envelopes be reused multiple times?
Yes. The reinforced metal clasps are engineered for repeated opening and closing, making these envelopes cost-effective for internal routing, file circulation, and document management workflows where reusability extends envelope lifespan.
How do I achieve a secure, permanent seal?
Simply moisten the gummed flap and press firmly closed. The gummed seal creates a tamper-evident barrier ideal for confidential or compliance-sensitive documents. The metal clasp provides additional security for multi-use applications.
Are these envelopes compliant with shipping and mailing standards?
Yes. The 28 lb. kraft paper construction meets standard mailability requirements and USPS/carrier guidelines. The 9" x 6" dimensions fit within standard envelope category specifications for cost-effective postage rates.
What's the difference between these and standard manila envelopes?
These kraft clasp envelopes offer durability (28 lb. woven paper vs. standard 24 lb. stock), reinforced metal clasps for reusability, and a gummed permanent seal option. This combination makes them ideal for high-traffic mailrooms and document-intensive operations seeking durability and cost control.
