When do you need a gel rollerball refill?
You use a gel rollerball refill to make your empty Pentel gel rollerball pens ready to write again. Instead of buying a new pen, you simply replace the refill and your pen writes like new. This is more economical and more sustainable than buying a complete new pen every time.

Why choose this 0.35 mm line width?
With a line width of 0.35 mm you get a fine, precise stroke that is ideal for detailed work. This width ensures sharp lines when taking notes, making technical drawings or when you need to write in small spaces. The gel formula gives you the comfort of smooth writing without pressing too hard.

Checking compatibility with your Pentel pen
This KFR7-A refill fits specifically in the Pentel models Hybrid Gel Grip DX K227, Hybrid Gel Grip K157, ERGoNoMiX KR507, Sterling K600 and Oh!Gel K497. Check the model number on your pen before you order – you will usually find this printed on the pen holder itself.

Practical tip for replacing
Unscrew the tip of your pen and pull the empty refill out. Insert the new KFR7-A refill straight in and screw the tip back on. Make sure the refill sits fully in the holder before you reassemble the pen, otherwise it may leak or not write properly.
