N.B. If you are buying the pink rollerball to match the pink fountain pen and mechanical pencil the colour of the rollerball is slightly different. The box that the Pink rollerball comes in says that it is red however the pen inside the box is actually a dark pink. It is a slightly darker colour pink than the fountain pen so that you can identify the rollerball from your pink fountain pen or mechanical pencil.
