Not black and white

This Nordic Knit polymer perfume case from Francoise Haon (Arliane) is black and white, of course.
What’s not clear is if the pattern is the result of mighty impressive canework or some other technique.
Patterns as precise as this make canemakers envious. Could she have extruded the tiny components? We’ll have to wait to see if Francoise gives us a clue. Take a look at the rest of Francoise’s Nordic line on her blog, her online shop and Facebook. What’s your guess?
