Frequently Asked Questions
Will a 6.5 x 4.5 mailer fit a standard folded greeting card?
Most single folded greeting cards and small prints fit a 6.5 x 4.5 mailer, especially if you use a simple cellophane sleeve or backing board to add rigidity. Measure your card folded and allow a few millimeters for protective sleeves or backing.
Do these rigid mailers need extra padding to prevent bending?
Rigid mailers are designed to resist bends, but for fragile cardstock, heavy embellishments, or multiple cards in one envelope, add a thin backing board or use a cellophane sleeve. Larger framed items should use the heavier 13 x 18 option for best protection.
Can I stamp or print directly on the kraft or white surfaces?
Yes. Kraft surfaces accept rubber stamps, ink, and stickers well for a handmade look. White rigid mailers are better for printed labels, branded stickers, or clean promo stamps. Test your ink/pad on a sample to avoid bleeding.
