What does 'Gusset' mean?

A gusset refers to the expandable sides of an envelope, designed to accommodate bulkier or thicker contents. Unlike standard flat envelopes, our string and washer gusset envelopes feature 25mm pleated V-shaped sides, allowing them to expand and securely hold items such as booklets, catalogs, or multiple documents with ease.
