I ordered this box of Washi Film from Analogue Wonderland, a great online film shop, based in England. I have tried a couple of rolls so far, so I will add posts about them later on.
According to their site, Film Washi was launched in 2013 and is the world’s smallest company to produce photographic materials. The company specialises in handcrafted film making and industrial film conversion. I have links to both Film Washi and Analoguewonderland below.
