Jam jars from Japan?

Lots of quirky light fittings with a 'found object' feel have emerged over the past few years.  Loved these light-filled preserving jars just hanging about at Superdry.  At first glance you might think this is a Japanese denim brand that dries faster than you can say sashimi.  Actually it's British.  They've opened at "Chad-Vegas" (in more formal language that would be Chadstone - The Fashion Capital, Melbourne).
