Dunno if it counts, but: an 'A4 printable magnetic ink jet sheet'. Gonna see if I can carry out a daft idea to magnetise minis and switch them between skirmish bases and unit bases. It's got a bit of a weak bond through the plastic packaging, but I wonder if it's strong enough to hold plastic minis, if it's stronger doubled over, and if I can boost it with a couple of rare earth magnets.
