Cello Butterflow Classic Roller Pen Set | Pack of 4 Roller Pens | 2 Blue & 2 Black Ink Colour Pens + 2 Jumbo Refills | Smooth Writing Experience | For Students and Office Use | Best Pen for Exams

This pen. Feels like heaven built quality, ink, leakage, color of ink is top notch, and also it has way better water resistance compared to v7, and it's value for money asthe ink is very big and last very but I liked if it has 3 blue pen and one clack my 2 black and refill is new and it has outstanding grip and the color of pen body looks so good. EVEN MY SST WHEN MY SST TEACHER BORROWED IT SHE SAID IT HAS VERY GOOD INK FLOW AND TIP IS VERY GOOD. I generally don't write big review but this thing deserves it and it way more cost effective than cheap 10 or 5 rupee pen JUST BLINDLY GO FOR IT

Very Smooth. Quality is also good.

Exactly the pen I was looking for. Accurate writing tip without any smudging.

If you want to buy this don't hesitate it's nice it's good pure smooth gel ink and better than v7 because v7 leaks and it doesn't leak also value for money but they don't sell cartridges with it or ink it only comes pack

Perfect for handwriting practice but ink empty very fast and cheap plastic but overall it is good

Good to use

Nice pen to write in exam smooth and fast, but not as much as smooth

This pen is of good quality, easy to hold, and writes smoothly. The dark ink gives a shiny finish and is even darker than the V7. There’s no leakage.
