Great pens. Highly recommended.
Love these. They improve my handwriting and they last a really long time. The 4 pack is great value and I'm very happy with them.

Not 0.3 but just as good. Good pen.
Great pens. I had the 0.3 before, but no longer available, but these 0.4 pens are just as good. They work great when writing, and also on Tech Drawings (for which I use them) I bought 'new' pens cause it was cheaper that the refills. Who knew! Buy one, give it a go. They are good.

Wouldn't use another pen
My absolute favourite pens! I am left-handed and usually find that the ink doesn’t dry in time and ends up smudging, but with these pens the ink dries super fast and prevents that. I use them for annotating in books and have noticed they don’t bleed through the pages, which is something I’ve had issues with in the past. The tip is quite fine, making it ideal for notes, and the pen itself is very comfortable to hold and looks sleek. They’ve also lasted me a long time and haven’t run out yet!

All of the pens and inks are blue
Despite the multi colours of the pens themselves, their contents and the spare inks are all in blue; no reds, pinks, greens etc. The image could be misleading to people, but I wanted blue anyway, and they all work just fine.

Smooth, precise, and great value
I’m really impressed with these Pilot Gtec gel pens. The 0.4 mm tip writes beautifully with smooth, consistent ink, making every word look clean and professional. They’re perfect for detailed work, note-taking, or journaling, as the fine tip allows for precise, controlled writing. The ink colours (black, blue, red, green) are vibrant and easy to read, and the gel flows nicely without smudging. I also love that this pack of four gives excellent value — it’s always handy to have multiple pens ready for work or home use. Overall, these pens are high-quality, reliable, and a pleasure to write with. I’ll definitely be buying them again.

Absolute Lieblingsstifte!
Diese Stifte habe ich schon sehr oft verschenkt sie schreiben wunderschön, weil sie so dünn sind und sie halten sehr sehr lange. Ich zeichne damit auch sehr viel. Meine Lieblingsstifte!
