Pilot FriXion Ball 07 BLRT-FR7 retractable erasable rollerball.
FriXion Ball uses the same brilliant thermosensitive ink as the rest of the range. It erases cleanly and completely via the heat generated by the friction of the eraser on the top of the pen. The eraser avoids getting in the way of the retract mechanism, which is instead actuated by the pocket clip.
There’s a neat little design detail where the ‘X’ in the FriXion logo turns from barrel colour to yellow when the tip is extended.
FriXion Ball 07 features a barrel colour that matches the ink colour and a dimpled rubber grip section. 0.7mm tip writes a medium line.
