Primary Blue

Clear, vivid color gives invitations, announcements, business correspondence, and creative paper projects a primary blue look. Primary blue JAM Paper envelopes come in 30 lb A2, #10, several square sizes, and a larger document style for broader printed materials. Semi-transparent construction lets enclosed cards or inserts show through subtly while maintaining a recognizable blue presentation.

For cards and inserts with balanced proportions, primary blue square envelopes appear in 5 1/2 x 5 1/2, 6 x 6, and 6 1/2 x 6 1/2 inch sizes. These translucent styles fit invitations, photographs, greeting cards, announcements, and layered stationery. The bold color fits birthdays, school events, promotional campaigns, themed celebrations, and artistic mailings that should stand apart.

Beyond square mailings, A2 primary blue envelopes coordinate with invitations and response cards, while #10 square-flap styles fit business letters and notices. A 9 x 12 inch booklet envelope opens along the long side for reports, certificates, brochures, and printed materials. These lightweight translucent choices work across personal stationery, office communication, event details, and presentation documents.
