Transform any newsletter, announcement, or invitation text into your own unique creation by printing it on our Birthday Letter Papers. Our Letter Papers are colorful, one-sided sheets that measure 8-1/2" x 11" the same size as copier paper and easy to print with almost any computer and printer. The paper is 28-lb. bond, a high-quality stock that s noticeably heavier than the 20-lb. bond weight of most copier papers. We've pre-printed the design for you in brilliant full color. Plus, because we can print the designs from edge to edge, your printed documents will look much more professional than those printed from start to finish on a home- or small business-size printer. 25 sheets per pack. Envelopes not included.
