The 3-in-1 Multifunction Pen from Craft Design Technology is like the grown up version of those plastic multicolor pens we all had as kids. Simply twist the barrel to change from black ink to red ink to a mechanical pencil. It uses a unique oil and water-based ink formula that’s long lasting and creates a super smooth writing experience. The metal body is decorated with the brands signature graphic pattern which provides a nice, comfortable grip.Refills available hereFeatures:3 functions: Black ink, Red ink, Mechanical pencil0.5mm ink / 0.5mm
