uni-ball Eye UB-150 0.5mm Roller Ball Pen | Blue Ink, Pack of 10

I used these for writing my CA exams. The pens are very smooth and last forever. They are made in Japan and bear all the hallmarks of Japanese quality. My handwriting quality and speed improved slightly while using these pens. That being said, I use these pens only for important occasions like exams as the pens are non refillable (use and throw) and it is best to reduce pollution. Also, they are a bit more expensive than the average pens but the quality makes them totally worth it!

Ideal pen, I particularly liked it

These pens are definitely a good buy the ink is smooth writing with them are flawless, using them for the past 1 year was really a nice experience clearly a worthy investment in stationary if you are a sophisticated Japanese stationery enthusiast and definitely go for product for regular as well as professional use.

Very good

Fantastic pen I use a lot of, expensive pens like parker but this one is my favourite one! If you reading my review just buy this product you never fell regret! Thanks 🙏🏻 Uni- ball for great technology.

Good

A smooth writter, with non stop ink flow. Looks classy and no problem for leakage. Must buy 👑

bought this pen with anticipation but was disappointed instead. the writing was not comfortable at all, yes it was indeed waterproof but the writing was not good for the given price range. I expected a lot from Mitshuba, as I am an avid pen user of this company. good pen but not recommended.
