Keep envelopes securely closed and protect their contents by using Clasp Envelopes for your business mailings. The rust-resistant metal clasp and reinforced hole prevent the envelope from being accidentally opened in transit. Of course, Clasp Envelopes also have heavily gummed flaps with very strong adhesive for another layer of security. Choose from classic white or brown kraft paper for a simple, durable envelope, or stand out with colored envelopes made of heavy weight paper.

Convenient ordering system and responsive owner; responds personally when I have questions. We ordered standard clasp envelopes and product was as expected. I especially like the responsiveness I get when I have questions.

We've always used these types of envelopes to hold personalized photo buttons. This is the best brand we've tried yet. They're a nice bright white, the rounded corners prevent paper cuts, and the fold down flaps are even pre-creased. Very happy with the product.

These envelopes worked perfect for what we needed. We paid for expedited shipping with out realizing we had to pay extra for expedited processing, so we were a little delayed in the the time frame we thought it would be here. But other than that, they worked great! I do love envelopes.com because their customer service is unmatched!!!
