Custom envelopes get noticed. A great-looking envelope stands out and makes people want to open your letter. Add a logo, photo or tagline to enhance your company image. Use printed color envelopes with business cards & letterhead for a complete identity package. We print our envelopes on 70lb premium and linen uncoated paper in sizes: 5.25"x7.25", 9"x12", and 9.5"x4.125".
