Envelopes worlds good creations. These are security tinted envelops. Its function is to mail your bills, whatever you put things in an envelop. Everyone sees all types of envelops: big, small, yellow you name it. I think the type of style of design this product fits in is Contemporary and the typography is modern, clean, simple. I think the typeface might be Helvetica. Mostly everything has this typeface, it's the default of everything. The artwork is simple, contemporary, functional. What attracted me to this was because we talked about contemporary era during class  and new modern products are developed everyday.
