iPhone, Android, Web & Tablet Whiteboards! If you design apps for a living you’ve had your share of whiteboard sessions. Boxes, circles, and rectangles everywhere.

Now you can take your typical whiteboard session up a notch with these to-scale device/browser whiteboard magnets (also available in vinyl ez-stick decals!).
