PENCILMARCH Erasable Pens Refills Black Pack of 9, Rub Out Pen 0.7mm Tips, Refillable Rollerball Erasable Pen for Handwriting for Students, Kids, and Adults Using for School Office Supplies

Very useful

The nibs are too fine. I use these pens abd refils alot, but prefer thicker nibs

Generally really good value. Ink flows well and rubs out really cleanly without smudges. Top tends to fall off if you put it on the other end when you are writing - especially when you try to rub out with it. Really pleased you can refill rather than throw away.

Value for money. Saves buying more pens.

Value for money. Much better to buy refills than new pens.

As some have mentioned, these fit the Frixion pens perfectly. Ink flows well and have not had any bother with them so far.My daughters use these in school and seem to go through them so fast so to get these items at less than half the price of the Pilot refills...its a no brainer.

These refills are excellent value for money and they work well. I do a lot of sudoku puzzles so I am frequently needing to refill my pens - these refills are so easy to use.

purchased in error, thought I was purchasing actual pens. Once they arrived I realised my mistake and ordered set of pens which I must say are lovely to use, great quality and very happy with them
