A birthday card shaped like a vintage mailbox, from the Korean brand Paperian, with spaces for To, From and a message, so there is somewhere to put the words rather than a blank expanse to fill.

The card is 13.7 x 7.5 cm on a substantial 230 gsm stock and comes with its own matching envelope at 16.6 x 8.5 cm.

Small enough to tuck in with a present, good enough to keep afterwards.
