From the page: Giha Woo designed a pen attachment that can help you draw straight lines. Called the “Constrained Ball”, this attachment can be easily attached on any pen and can help you draw straight lines, horizontally or vertically.
This little wrist holder securely holds your cell phone or smartphone, and even lets you see and interact with the screen.
