It writes reliably without skipping. I am a nurse and I use a pen constantly and 90% of the time I’m writing on surfaces that aren’t normal paper...lab labels, paper towels, wound dressings, etc. this pen writes on everything. My favorite part of this pen is that the ink doesn’t smudge at all!! I have never ever had a pen with ink that doesn’t smudge after writing on a lab label but by golly this one does! The writing is sharp and precise, which I like. As others have said it’s not the boldest or brightest ink. For me that is definitely a fair trade off for clean precise writing with zero smudging! Review: Best ink pen - The Power Tanks by uniball are the best ink pens to write from any angle and they are smooth with no skipping, blobbing or smudging. Best all around pen I’ve ever used. I really like that now you can get them in the .7 and not just the 1.0 tip. I don’t think you will be disappointed with this pen. ## Features - Uni Power Tank, Pressurized Refill Ballpoint Pen, 0.5mm, Blue body, Blue ink - w/tracking number from JP Post ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000W9C0I4 | | Additional Features | Refillable | | Age Range (Description) | All Ages | | Age Range Description | All Ages | | Best Sellers Rank | #84,549 in Office Products ( See Top 100 in Office Products ) #630 in Ink Pen Refills | | Body Shape | Cylindrical | | Brand | Uni-Ball | | Brand Name | Uni-Ball | | Closure Type | Snap | | Color | Blue | | Customer Reviews | 4.6 out of 5 stars 252 Reviews | | Drill Point | Fine | | Grip Type | Smooth | | Hand Orientation | Ambidextrous | | Included Components | Refill, Packaging | | Ink Base | Water | | Ink Color | Blue | | Item Dimensions | 5.91 x 0.31 x 0.31 inches | | Item Weight | 0.01 Grams | | Line Size | 0.5mm | | Manufacturer | Uni | | Material | Plastic | | Material Type | Plastic | | Model Number | SN200PT07.33 | | Recommended Uses For Product | Writing, Note-taking | | Style | Ballpoint | | Unit Count | 1.0 Count | | Writing Instrument Form | Ballpoint Pen | ## Product Details - **Age Range (Description):** All Ages - **Brand:** Uni-Ball - **Color:** Blue - **Ink Color:** Blue - **Writing Instrument Form:** Ballpoint Pen ## Images ![Uni Power Tank Ballpoint Pen - 0.7 mm - Blue Body - Blue Ink - Image 1](https://m.media-amazon.com/images/I/61MtedxrucL.jpg) ## Questions & Answers **Q: Is this the pen or the refill for the pen? down the page under the heading "what's in the box" it says "ink cartridge.** A: Pen **Q: Is the ink waterproof? Can it be used with a waterproof notebook?** A: Description Uni Power Tank Pressurized Refill Ballpoint Pen 0.7mm Blue body Blue ink Ink has been pressurized 3000hPa, which allows you to write even the pen is upside down, on a wet paper, temparature -20C degree. **Q: does this pen write bold** A: The description plainly says it is 0.7mm, which is what all Medium point pens are, and that's all I use for my main pens. This is a fantastic pen, I've ordered it several times, to be able to lie in bed and write upside down on my bedside notepad, of many things I think of I want to do the next day. However, I believe I recall it being available as a 1.0mm point, which is what most all BOLD tip pens are, or as a 0.5mm Fine point. **Q: I assume this is a dozen blue pens?** A: I also assumed this was for a dozen pens. Received my order today and it was only one pen! Very disappointed!!! Will be checking into a return immediately!!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for a nurse *by A***. on February 18, 2020* I love this pen. It writes reliably without skipping.
