Symmetrical and stunning are these 5 1/2 x 5 1/2 Square Envelopes. Most envelopes do not have the beautiful balance that our square envelopes achieve. And with this square size comes the straight flap. The combination makes your envelope as contemporary and modern as it gets. Whether you're using these to dress up marketing and promotional materials for your business or use them for unique invitations for family parties, the versatility of these envelopes will certainly work in your favor. But just remember, most square envelopes need additional posting due to the uniqueness of the envelope.
Our collection of 5.5 x 5.5 Square Envelopes is vast, having almost every color of the rainbow and even more! And since color is what people see first when they search through their mail (other than bills), we decided to sort this page by color. From dark shades to light, you'll find one that matches your occasion perfectly. We also carry envelopes with a translucent finish, making your content semi-transparent. This way, your recipients will get a hint of what's inside even before opening the envelope. All are complete with a straight flap to make your style the most contemporary and balanced. So start square shopping now!
