What does a gel roller refill do?
A gel roller refill allows you to keep using your Pentel gel roller pen when the ink runs out. This is an eco-friendly and cost-saving solution, as you don't have to buy a complete new pen every time. The refill brings your pen fully back to life.

Why this red 0.45 mm variant?
This particular refill has a line width of 0.45 mm with a ball diameter of 1.0 mm, resulting in a fine yet clearly visible line. Red is ideal for highlighting important points, making corrections or distinguishing between different categories in your notes and documents.

Compatibility with your Pentel pens
This KFR10-BO refill is specially designed for five different Pentel models: the Hybrid Gel Grip DX K230, Hybrid Gel Grip DX Metallic K230M, Hybrid Gel Grip K160, ERGoNoMiX KR507 and Sterling K600. You can only use this refill in these specific Pentel pen models.

Practical tip for replacing
Check the model number on your pen before ordering the refill - this is usually printed on the pen itself. The refill has reference number KFR10-BO, where "BO" stands for the red colour. Replacing the refill is easy: unscrew the pen, remove the empty refill and insert the new one.
