Color/Body Material: Strawberry & Cream, ABS resin Ink Color: Black This is a LAMY Safari rollerball pen. It is a set in Strawberry/Cream. Rollerball pens use water-based ink, offering a smooth writing experience and allowing for writing with light pressure. I have never used a rollerball pen myself, so I don't know much about the product. I have included as much information as possible for this listing, so I would appreciate it if those who understand the situation would consider purchasing it.
