12 x Euro Format Rollerball Pen Refills - Compatible Sheaffer, Caran d'Ache , Faber-Castell, Monteverde, Schmidt, Schneider (black)

Have now tested all of these and they are well worth the money - 12 rollerballs which fit my Ferrari/Sheaffer pen. The ink capacity seems slightly less than the genuine items but you do get 12 for very little money. The quality of the script is every bit as good as the proper tips so far... As I have removed the little plastic blob which seals the tip of each refill I am storing the 11 spares in a vitamin-tablet-tube until needed.
