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.
Quality excellent. Did not have original size requested but a substitute was given.

Excellent! I thought I'd only need a few of these envelopes but now I'm finding many uses for them. They're transparent and I can store old photos that I don't want to put into albums in them.
