The JAM Paper 13.5" x 13.5" white envelope features a closure that can be easily opened and closed for your convenience. Don’t let the name fool you, these are anything but regular. But square, well we can’t say no to that. And we don’t think it’s a bad adjective anyway. Actually, we never figured out why being ‘square’ is such a bad thing. Especially when it involves envelopes. So embrace your inner nerd (or ‘square’ personality) by picking up one of these! Square envelopes are inherently unique, especially looking at them next to that simple, standard envelope. So when you want to stand out, go for our square envelopes and make that square factor become back in style. Because rectangles are SO last year. And the pure, white color will match any kind of announcement, greeting card, and all of those hard to fit invitations. Whether you want to compliment your ivory invite or contradict that black invite, the white will match! Available in over 15 sizes so that every occasion is accounted for.
  • Blank interior for personalized message
  • Smooth paper finish for a sleek appearance
  • Straight-flap gum closure helps keep contents secure
  • Made of 28-lb paper
  • Finish: Smooth
  • Envelope Flap: Straight Flap
