I've seen these boxes all over pinterest over the last week and I think they are really good. I love the simple and plain style of showing what the product is. The use of a single colour not only, is cheap, but works really well in reinforce the straight to the point use of the product in this case. I like how the image of the product is in white, whilst all the colour is the surrounding area, this would be something I would like to incorporate into my packaging or logo design.
