Gusseted envelopes have a fold on the flap and sides and offer more width and space inside. The gusseted envelope is great for sending items or documents that are thicker than usual and cannot be sent in a conventional envelope. You can find them in a variety of sizes and with different options, for example, with or without a window. Moreover, in recent years, the material used to make gusseted envelopes has been strengthened to prevent them from tearing easily. So if you want to send an important product or document without it getting damaged, this is an excellent option.
