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.

I didn't care for the line density of this pen. Perhaps I would've chosen 0.7 if I'd known the lines would be so weak on the 0.5. Nice colors on the barrell. I like the rubber grip near the tip. The erasure feature works well. I would've probably returned these but I used them. Overall not really happy with these pens.

This pen doesn't work well. It is very difficult to click to get the pen to open for use.
I wnated to try it becuase i grandaughter and I ususally are all working together at the table and I thought if they were good pens I could get each of us a different design.
Not happy with this particular item. The only good thing is that it is cute!

I'm on the Pilot FriXion "bandwagon". This is a close second to my Uni-ball but the 0.5 is perfect because I write small and this doesn't lay down a lot of ink. I will be replacing the black ink when it's done with the blue/black refills - I'm obsessed with Blue/Black ink !

I love the feel of this pen - it is very smooth and consistent, and the ability to erase is just a very nice bonus. I use this pen primarily for quick sketches. Though marked as 0.50mm, this feels to me more like 0.40 or so.
