This ballpoint pen is 3 colors and 4 cores, which are black 1.0mm and 0.7mm, red and blue are 0,7mm. As the 0.7mm tip writes fine lines and the 1.0mm writes medium lines, it helps to use different character thicknesses according to the purpose. Also, the ballpoint pen has a rubber grip which is comfortable to reduce the burden and this grip makes it easier to hold. 2 ballpoint pens in 1 packaging box, great deal!
