Choosing the Correct Starburst Envelope

Choose Item W7418 for Lime 9″ x 12″ Booklet Envelopes

Item W7418 is the correct choice when you need a 9″ x 12″ open-side envelope in Starburst Lime. The wide opening accommodates flat documents, and each carton contains 500 bulk-packed envelopes.

Booklet Envelopes vs. Catalog Envelopes

Booklet envelopes open along the longer edge, making them convenient for inserting presentations, brochures, and multi-page documents. Catalog envelopes open along the shorter edge and may be preferable when documents should enter from the top.

Understanding the USPS Reflectance Designation

The manufacturer identifies Lime as a USPS Reflectance Approved Starburst color. This designation concerns the paper color’s reflectance characteristics; the mailability of a finished piece still depends on its address placement, postage, contents, dimensions, and applicable postal requirements.
