Saves you buying a whole brand new pen, just buy a single refill! This listing is for x1 single refill. Compatible with the 0.7mm tip (ones that i sell) 

 

As i use my frixion pen alot of felt it does run out quickly so i've always got these on hand to save me grabbing the nearest biro which doesnt remove with heat - haha!
