Every Mohawk envelope features a discreet die-cut "M" on the inside seam, which is revealed by holding the envelope up to a light source. "The ‘M-notch," the company says, "is a symbol of Mohawk quality and assurance, backed with world class service and support."
Saybrook envelopes are available in bright white wove, recycled white wove, brown kraft, and gray kraft envelope papers, in basis weights ranging from 24 lb./90 gsm to 28 lb./105 gsm.
