At its heart, this is a pinhole camera in DIY form, using a simple precision laser-cut 0.4mm pinhole to capture images onto medium format film.
That old school exterior comes in that kit form, which is screen printed and die-cut individually by hand onto thick recycled card, with instructions (obviously) included as a guide to putting it together. You also get a spare medium format spool (reclaimed from 'some of the best darkrooms in London'), but you don't get the 120 film and craft glue to finish the job. But both should be easy to pick up.
Talking of picking up, you can secure this vintage-style gem for £38 online.
