Muji stamp kit
A cup of coffee at our friend Angus' house led us to this latest tasty bit of goodness from Muji.
It comes boxed up with a couple of ink pads (red and green), and is set in what looks like a medium to bold weight of Helvetica (oddly, the pic on their website is of a different typeface, but we could only see this one in their shop).
Because there's no frame or device to mount the stamps into when you print with them, they tend to create a fairly widely spaced and uneven text (depending on how hot your hand to eye coordination might be).
Stampalicious.
