5 1/8 x 5 1/8 Envelopes for Cards, Photos & Prints

JAM Paper 5 1/8 x 5 1/8 envelopes offer a close-fitting option for invitations, greeting cards, photographs, artwork, announcements, and other flat printed pieces. Their balanced dimensions help keep contents neatly enclosed when folding is not desirable. This size works well for both stationery and more specialized paper or photo projects.

Parchment Envelopes & Heavyweight Photo Mailers

White parchment brings texture to invitations and stationery, while the heavyweight white photo mailer adds rigidity for photographs, artwork, and flat documents. These two styles serve different purposes within the same dimensions, giving shoppers a choice between a traditional paper envelope and a more protective mailing option.

Square Mailers for Photographers, Events & Business Use

Photographers and artists can use the rigid style for prints and finished work, while event planners can pair parchment envelopes with invitations and announcements. A Peel & Seal closure on the photo mailer helps simplify packing for customer orders and professional deliveries. The 5 1/8 inch dimensions keep smaller flat pieces secure without requiring an oversized enclosure.
