Red Square Envelopes

Bold color gives square cards, invitations, announcements, greetings, and promotional mail an immediate visual impact. JAM Paper red square envelopes range from compact 3 1/4 x 3 1/4 inch styles to larger 9 x 9 inch sizes, accommodating a range of stationery sizes. Bright red and deeper garnet tones can suit everything from festive correspondence to formal event pieces.

Christmas cards, Valentine's Day notes, party invitations, and seasonal announcements pair naturally with red packaging. Darker shades can create a more subdued look for business events, formal celebrations, or branded mail. Coordinating red envelopes with white, black, gold, silver, or patterned stationery can create strong contrast without extra decoration.

Many styles feature Peel & Seal closures for convenient preparation, while additional closure types are also available. Paper weights and size choices provide flexibility for small cards, larger invitations, and substantial square stationery. Businesses, event planners, and individuals can turn to red square envelopes when correspondence needs a distinctive color before it is even opened.
