Pack of 50 premium mini envelopes. Each envelope is 3.5 x 2.3 inches in size (90mm x 60mm), the perfect size for gift cards, wedding place cards, party invitations, thank you notes, flower arrangement notes, business cards, and many more miniature envelope needs. Please kindly note that these envelopes are too small to mail via USPS by themselves, and would require being put in a larger mailing envelope to send via post.
