Markers, pens and ink straight from the bottle -- they are often connected to writing. These materials can be for the office, for school and for little stationary. But don't stop there! They are very versatile and can be used for art and design too! As artists and designers need quick illustrations to pitch ideas to art directors, these tools are great for those fast turn-around times. Sometimes, they can be used throughout the whole art process. You can be very loose or tight. It's all up to you!
