I use pens so much as a risk assessor. Used so many varies types from bic, papermate, uniball, zebra, sharpie, staples, ypo, poundshop multi bags and whatever else you can think off.These were my first of this type brand and wow this is a stunner of a gel pen. Its a rich black ink and smooth flow. Not a single smudge upon writing. It was smooth to use and felt the price for the pack was a good price as i was really happy to use and be happy to use.They are so close to the sharpie gel pen which is my favourite. But this is so so close and I must say a nice style in look too.
