A firm mailer for flat garden cards

ProLine 5 x 7 Rigid Photo Mailers give pressed flower cards, small plant photos, seed packet images, and flat notes a firm cardboard cover. The mailer helps a finished card stay flat while it moves from the card table to a basket, shelf, or mailbox.

The 5 x 7 size fits many small photo prints and card projects with a tidy amount of room.

Useful after sleeve packing

A clear card jacket can protect the card surface, and a rigid mailer can give the finished piece a firm outer layer. That pairing works well for garden swaps, thank-you notes, flower press gifts, and small archive mailings.

The self-seal closure keeps packing straightforward during a batch session.

Plan space and postage

The 200 count case is helpful for repeated use, and it needs shelf space. Keep a small working stack near the card station and store the rest flat.

Postage rules vary by size, thickness, and destination, so check the mailing rate before sending a finished card.

What to expect

Rigid mailers are strongest when the card inside stays flat. Use shallow pressed pieces, smooth sleeves, and a light label so the finished package closes cleanly.
