The ink flows smoothly and the camera on the pen is able to pick it up

One of the little frustrations that come from owning a pulse echo or sky pen are the poor quality refills

Posted by a reviewer on Amazon

I have had them skip leak and fall out of the pens often

They write smoothly and dont leak if only they could spell

Before this refill i was constantly pressing down hard to write or i had to go over what i had written so that i could read my notes when i wasnt on my laptop

Please please buy these instead of livescribes refills

This was not a performance problem but very distracting and annoying when writing

Hated getting 5 refills but only using 4 since 5th is red ink
