Review: NOT a run-of-the-mill pen - Read before you buy - Its not a regular ball pen and you will surely be disappointed if you buy it expecting the performance of a regular pen. About me - I invest in stationery and buy unique products. I like the experience of getting new (& less known) pens and trying them out. About Uniball - Uniball is the world leader is pens and you may have used pens by this company. If not, please buy them and try - they are a delight to write with. About this pen - its a niche product with very fine tip (0.28 mm). Therefore the USP of this pen is its fine writing. And that's what you should buy it for. The weight is well distributed, the bottom being heavier that the top. And its very comfortable to hold. Pros Writers very smooth, like butter. The fine tip is a delight for those looking for a unique writing experience. Uniball quality shines through - as I said, they are world leaders in pens Cons The pen writes best at a particular angle; so you have to adjust accordingly. Like many ball pens, it takes a day or two to catch up and become smooth. Before that, you require patience. After that, its a joy to write! Since its a niche product, refill availability will be a problem. I plan to buy some from desertcart and stock up. Price is high - but its a niche product, not your regular 10-rupaye-wala-ball-pen-available-at-nukkad-shop. So if you know what you are getting into, buy it, give it a few days and enjoy the ride! Imagine the pen being an orchid - requires care and watering and will wither away in harsh conditions; but when it blooms, its a joy to watch! Hope the review will help make you an informed purchase decision. This pen is not for everyone!
Review: The pen is not for everyone - There are many factors which this pen requires. Many people have the audacity to write horrible things about a pen which is strictly for fine pen writers. And this pen requires you to have an active interest in fine pens or else you just won’t find it as appealing to hear as when you actually buy it. Now for the factors: 1) This pen strictly requires an angle to write perfectly, any other angle will make the ink come in an uneven amount. 2) The ink is slow to finish but it requires 1,700 to buy a new ink so only use this pen on special occasions. 3) This pen is sensitive, if you exert too much pressure, it will bend/break. So be gentle. 4) If the pen doesn’t work on the first try, don’t give up, it just means the ink is dry or your angle is incorrect. That’s all thanks for looking at my review
