If you order a couple of cards, we usually ship them in one of these mailers (though, this is not guaranteed). They are solid and well-tested for world-wide mailing. If you plan to mail one of our art cards to someone or, just want to keep them in good condition, we recommend one of these mailers.
The small size is 6 inches by 8 inches (6″ by 8″) or, about 15 CM by 20 CM.
The large size is 9.75 inches by 12.5 inches (9.75″ by 12.5″) or, about 24 CM by 31 CM.
Please be aware of the size of the card for which you are ordering a mailer.
