JAM PAPER Premium Dark Gray Invitation and Business Envelopes

These JAM Paper premium envelopes in dark gray deliver a coordinated, professional look for personal and business mailings. Constructed from acid-free 28 lb paper, they resist yellowing and offer smooth to textured finishes for a refined appearance. Each envelope features a moisture-activated gummed closure—straight or square flap—to create a secure, tamper-evident seal suitable for wedding invitations, thank you notes, holiday cards, RSVP cards, announcements and business correspondence. Part of JAM Paper's Booklet Invitation Envelopes and Color Square Invitation Envelopes lines, these envelopes combine durable paper construction with classic closure styles for versatile stationery use.
