Cello Butterflow Simply Ball Pen Set | Pack of 25 Ball Pens | 20 Blue and 5 Black Ink Colour Pens | Smooth Writing Experience | For School and Office Use | Best Pen for Exams

Loved it , great pen , very smooth and fascinating ink flow but only for blue pens cause the black pen doesn't work that great like blue , but ya both are fine and great.

Very smooth and fast for writing. Good on white pages but its not dark ink.

Best quality of pen

Justice to its name .... Butter jaisa writing flow

20+5 pen present,But the old butterflow was far more better then this one, maybe the product is defectiveThe writing is very light, and the nib is also thick as compared to older pen.

Good

1. Most of the pens do not work. They lose their ink quality and pressure over time even if kept as new without opening the seal.2. Writes well for 1-2 pages, then the ink flow stops in half, still writes, but will be very light and hard to read, makes it irritating to write.3. In some cases completely stops writing and the whole pen will be thrown to trash.

Nice pen but among this 25 pics one is unable to write
