these were a few of my favorite 3.

the display pencil is actually holing the package closed. very well done. love the look and the materials.

this is a before and after. very clean look. switched to glass which is suppose to be "greener". maintain the brand identity while greatly improving the products appearance. i would pay like 1.50 for the can and 3.00 easily for the bottle.

this last one is awesome. just look at it.
