5 1/8 x 5 1/8 Square Mailers

A square mailing shape gives invitations, photographs, announcements, cards, and creative pieces a distinctive presentation. JAM Paper 5 1/8 x 5 1/8 inch mailers provide compact packaging for flat contents that fit naturally within balanced square dimensions. The size works especially well for boutique correspondence, special events, photography, and artistic mailings.

When delicate paper goods need added support, rigid constructions help reduce bending during transit. Peel & seal styles provide convenient closure for photographs, small prints, keepsakes, invitations, and other flat materials that deserve a more structured enclosure. Specialty paper options offer an alternative when presentation is the primary consideration.

Creative correspondence does not always need to follow a traditional rectangular shape. These compact square mailers suit greeting cards, announcements, professional prints, promotional pieces, and event materials that benefit from a closer fit. Their distinctive proportions add visual interest while keeping smaller contents neatly contained.
