#10 Envelopes - 4 1/8 x 9 1/2

Measuring 4 1/8 by 9 1/2 inches, #10 envelopes are the everyday benchmark for mailing standard 8.5 x 11 documents folded into thirds. JAM Paper brings a fresh perspective to this commercial staple. We pair reliable office utility with vibrant shades that make sure direct mail and everyday office correspondence capture immediate attention.

Safeguard financial statements with interior security tints, or speed up monthly billing runs using single-window formats that clearly display recipient addresses. In addition to crisp bright white and brown kraft, we offer saturated jewel tones or soft pastels to reinforce company branding and special promotions.
