What does this product do?
These Pentel refills are designed for gel ink rollerball pens and make your pen write like new again. You need these refills when your current pen has run out and you want to avoid having to buy a complete new pen. The gel ink gives a smooth writing experience in red.

Why choose this 0.3 mm variant?
The 0.3 mm line width produces a fine line, ideal for precise writing where accuracy matters. With a ball diameter of 0.6 mm you get a stable ink flow that is suitable for detailed work, taking notes, or documents where you want to add a subtle red marking.

Reliable gel ink technology
These refills use gel ink, which means the ink becomes fluid while you write but dries quickly on paper. This prevents smudging and gives a clear, consistent red result. The ink adheres well without bleeding through to the back of the paper.

Checking compatibility
These KF6-B refills are specifically suited to the Pentel Hybrid Gel Grip K116 and Hybrid Roller K106 pens. Before ordering, check whether your pen has one of these two model numbers, as these refills only work with these Pentel gel ink rollerball models. The reference code KF6-BO refers to the same refill in a different packaging.
