When do you need a gel refill?
A gel refill is used to replenish your Pentel gel pen with fresh ink when it runs out. This is a sustainable choice because you don't have to throw away the entire pen, but only replace the refill. Gel pens are ideal for writing smoothly without applying pressure.

Why choose this 0.35 mm refill?
With a line width of 0.35 mm, you write fine, precise lines that are perfect for detailed work, notes or drawings where accuracy is required. The 0.7 mm ball diameter ensures smooth ink flow without the tip becoming too thin for everyday use.

Blue: the versatile colour choice
After black, blue ink is the most commonly used colour for business correspondence and schoolwork. It gives your text a professional appearance while looking less severe than black. For contracts and official documents, blue is often preferred because it clearly distinguishes original signatures from copies.

Checking compatibility
This KFR7 refill fits only specific Pentel gel pens: the Hybrid Gel Grip DX K227, Hybrid Gel Grip K157, ERGoNoMiX KR507, Sterling K600 and Oh!Gel K497. Check the type number on your pen before ordering, as gel refills are not universally interchangeable between different pen models.
