Butterflow Classic Gel Pen Set | Pack of 20 Gel Pens | 20 Blue Ink Colour Pens | Spring Tip | Smooth Writing Experience | For School and Office Use | Best Pen for Exams

It's so smooth and you can use this continuesly for maximum 1 years minimum 7 to 8 months. Value for money. Quality is very good. The ink will dry as soon as you write so you can use it as a ball pen.

The og pen very smooth .

the pen is comfortable to hold , the grip is sturdy , the issue with the pen is that quiet a few of them were not smooth at all , it works intermittently .

Great pens, wide tip, nice inkflow

Cello is a trusted brand in pens and this pen is good for regular use. Tends to smudge / blot on paper though.

As expected

if you want to buy cello butterflow buy it from a local stationery shop. if u buy it from amazon ur money will be totally wasted. half the pen is not working properly. the writing is not smooth. the ink will stop in the middle. pathetic and worst pens. i highly doubt whether they are original product from cello.

Vakue for money
