### ⭐⭐⭐⭐ 3 x Uni-ball Eye UB150 Rollerball Pens Micro o.5mm Tip 0.3mm Line Black Ink Customer Review
*by K***Y on 9 February 2014*

I chose this rating because the quality of pens were very good but, tiny fault, the delivery date was not reached. It took 2 days over the estimated delivery date, but I can't blame you. It was an estimate!!! What I liked about the product: *Good quality *Lasting time is very long *Smooth writing quality What I disliked about the product: *Ink smudges! (not good for left handers) *Packaging could of been better! All my pens had fallen out I would recommend this to all my school friends and family who work in an office as they last long and have a neat finish. I would hope that this review is going to help you achieve more customers (not that you don't have enough) and helps with any surveys that may be in place.
