Square Envelopes Make a Statement

Due to overwhelming demand The Paper Mill Store envelope department has added a huge inventory of various square envelope sizes. We found that all envelope square sizes are in great demand from our customers. We've added squares from 5 x 5 square envelopes to 9 1/2 x 9 1/2 square envelopes and in all sizes in between by 1/2 increments.

We have economical white square envelopes using Wausau Paper's Exact Ice paper and premium translucent square envelopes using CTI Paper USA's Glama Natural. Glama Natural is an Forest Stewardship Council certified paper so you can know that the fiber used to make this envelope came from well managed forests.
