Square Envelopes

Square envelopes are all about symmetry and balance, and each of the styles available is highly appealing to the eye. Choose a size from miniature 3 1/4" Square Envelopes to calendar sized 12 1/2" Square Envelopes. Most styles have square flaps, but a few have deep triangular contour flaps that nicely offset the Square Envelope. Select from several weights, sizes and a rainbow of colors, including some metallic square envelopes for an especially elegant touch. Keep in mind that when mailing square envelopes through the USPS, you will need additional postage because of the shape.

The quality is excellent & size was right for my home made Baby Shower invitations. The price was very good. I would recommend this product to all my crafty friends & I will be ordering more from your company the next time I need envelopes.

It's an odd size & color so it sticks out. "A gift for you" printed on it makes it ideal for lumpy mail that will catch my customer's eye!
