COLORS is a Japanese company which produces protective covers for gadgets, and their latest item features the artwork of legendary artist, Keith Haring. Bamboo material is not a common material found on protective cases, which gives this case its unique look. Furthermore, rather than using an ordinary method of printing artwork on its exterior, these cases are engraved by Haring‘s distinct illustration. Perhaps this case may be eco-friendly alternative to synthetic cases, and these will fit both the iPhone 4 and 4S. If you are looking for something different to accessorize your smartphone, head over to BEAMS in Japan to order this case.
