I wanted an interesting shape not just the typical rectangle or square, when I was researching different shapes these three looked similar to what I was thinking of.

These boxes are very different and make you want to know what is inside them, thats what I want to portray in my own packaging. The shapes gave me some great ideas for the shape of the box and what I could do for the packaging.
