The Ohto Multi-Smart is a multi pen that is slim and small, yet highly functional. Great for business or personal use, it's everything you need in one pen. Black, blue, and red ballpoint components, plus a 0.5 mm mechanical pencil, are all housed inside a sleek aluminum body. Despite how much is packed inside this pen, it remains wonderfully compact. Measuring at only slightly over 5 inches long, it's even thinner than many single-cartridge ballpoint pens. The inks, pencil leads, and eraser are all refillable.
Function indicators labeled "Black", "Blue", "Red", and "05" are located near the top knock button. The method of selecting a component is unique: simply turn the pen so that the indicator for your desired function is facing up toward you, and click the knock button down. For example, to select the blue ballpoint ink, hold the pen with "Blue" facing up as shown in the photo and click. To retract, press the narrow grooved button on the clip.
