The FriXion Ball Knock Design Series showcase modern and fun body designs! The pen features the same beloved thermosensitive ink found in other FriXion pens that can be erased by friction, but in a sleek, retractable body. Just push the clip to extend and retract the tip. The special rubber tip at the end allows you to erase conveniently without having to cap or uncap your pen. The pen writes smoothly and erases without a trace!
FriXion ink is a thermosensitive ink that can be erased by rubbing. Interestingly, erased ink reappears at temperatures below 14° F (-10° C). A freezer is cold enough to make this happen. Due to the thermosensitive nature of FriXion ink, we advise against using it for mailings, or leaving the written materials in hot cars or in environments that expose them to a lot of friction.
This pen contains black ink. Refills are available in additional colors.
