51 filament pieces do not necessarily mean 51 different colours.

4. Standard 1.75mm Nominal Diameter

Filament diameter matters because the pen’s feeding system must match the material size.

Some pens require different diameters or proprietary refill systems.

Always check the pen’s supported diameter before inserting the filament.
