6 1/2 x 6 1/2 Square Envelopes

Designed to hold layered cards, printed inserts, and specialty stationery, 6 1/2 x 6 1/2 square envelopes suit greeting cards, event invitations, announcements, and professional correspondence. The symmetrical shape gives personal celebrations and business mailings a distinctive alternative to standard rectangular envelopes. JAM Paper offers a broad assortment for both decorative and everyday uses.

Texture, color, and finish give this collection a wide range of looks. Smooth white and natural papers provide classic choices, while linen, translucent, metallic, and foil-lined styles add more visual variety. Gold, silver, black, red, blue, green, orange, and other shades support specific themes, while contour flaps provide another design option alongside traditional straight-flap envelopes.

Businesses and event planners can use this size for save-the-dates, promotional cards, customer announcements, holiday messages, and corporate invitations. Peel & Seal options help streamline preparation when larger quantities are being assembled. The broad selection of papers, colors, and finishes also makes it easier to coordinate envelopes with printed materials, event themes, or brand colors.
