Per questions. The box and label dielines are attached to the brief, so that should let you know the size.
Per the price and the 4 elements, please focus on just the single box of Sugar Crush, and make a design which has the ability to be adjusted easily to the other item called Sugar Crush Daily. So design just one box, and all the other executions can come after the contest winner is awarded.
Per imagery. We are wanting a very natural feel, use of leaves and other natural imagery would be helpful. This is a very expensive product (nearly $100 for 4.2 ounces). It is a highly specialized, clinically proven product which could be a life saver for Diabetics. So from an imagery standpoint, we should have some level of medicinal look, combined with a natural product look. We are totally open to color and graphic execution to attain this.
I hope that helped a little bit.
