Sadly this series of "self-printed" calendars and plant posters is a prototype only.
The creative behind this gem, Oscar Diaz, came up with the self-printing concept when he realized he could control the release of ink.
I totally love these; they are really, really different. Personally, I think we should all campaign for Oscar to come up with a advent calendar along the same lines and, dare I say it, come up with a non-tacky version.
