Renew Replaceable Refill Marker

Art and Stationery Supplies Design Renew Replaceable Refill Marker by Yunsong Liu Renew is a marker designed for quick replacement of the ink core. The pen holder is unscrewed with a twisting motion, so the tip separates from the core and a new core can be inserted without spilled ink. The twist mechanism keeps the holder in place when the cap is removed. Grooves around the fiber tip let the tip bend, which keeps full contact with the paper surface. The cap shape indicates the tip thickness, and matching cap and holder colors show the tilt direction of the tip. The body is made of plastic with a rubber section.
