The History of uni-ball In 1887 a man named Niroku Masaki started a small company making pencils in Tokyo. Almost 100 years later in 1979 the first uni-ball rollerball pen was created. Its quality and writing performance made it an instant hit in Japan and America. Fast-forward another 15 years to 1994 and the Eye rollerball that uni-ball is now known for was created. Since then it's popularity has continued to grow, making it one of the UK's most popular rollerball pens. Niroku's original 10 man 'Masaki Pencil Manufacturing Company' was rebranded 'Uni Mitsubishi Pencil Company' in 1952; today it employs over 3500 people and it's uni-ball pens are sold in more than 100 countries around the world. Review: Perfect pens. - I LOVE these pens, really love them. Not only are the colours really vibrant and pretty, but they write beautifully, and they let a really long time. I write every day and was really surprised by how long each pen lasted. They don’t smudge either. I’ll be only using these from now on. The line they give is quite thick, but I happen to like that. Truly great pens. Review: Nice set of pens - My daughter brought home a blue one of these pens as she uses it at school and I loved the way it wrote. It was because of this (& the fact I like to write using different colours for work) that when I saw this set I decided to treat myself. I’m really pleased with my purchase and the pens have lasted well so far. The ink flows out nicely and it does not bleed through the page while the colours are nice and vibrant. ## Features - Liquid ink rollerballs, assorted pack of 8 colours - Ideal for every day use in the office, school or home - 0.7mm tip, produces medium 0.5mm writing line ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00HW0KSOY | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | 60,907 in Stationery & Office Supplies ( See Top 100 in Stationery & Office Supplies ) 96 in Rollerball Pens | | Body Shape | Rectangular | | Brand | uni-ball | | Brand Name | uni-ball | | Closure Type | Click-Off Cap | | Colour | Multi-Colour | | Country Of Origin | Japan | | Customer Reviews | 4.8 out of 5 stars 1,419 Reviews | | Drill Point | Medium | | Global Trade Identification Number | 05012788003680 | | Grip Type | Contoured | | Included Components | 8 pens in different colours | | Ink Base | Water | | Ink Colour | Assorted | | Ink colour | Assorted | | Is the Product Left or Right Handed? | Ambidextrous | | Item Diameter | 0.7 Millimetres | | Item Dimensions | 2 x 1 millimetres | | Item Weight | 0.24 Pounds | | Line Size | 0.7mm | | Manufacturer | Mitsubishi Pencil Company | | Material | Plastic | | Material Type | Plastic | | Model Name | 153528624 | | Model Number | 153528624 | | Pattern | Single | | Recommended Uses For Product | note-taking, journaling, signing documents | | Special Features | Liquid Ink | | Style | 8 Assorted | | Theme | Plain | | Unit Count | 8.0 count | | Water Resistance Level | Waterproof | | Writing Instrument Form | Roller Ball Pen | | Writing Technique | rollerball | | Writing instrument form | Roller Ball Pen | ## Product Details - **Age range (description):** Adult - **Brand:** uni-ball - **Colour:** Assorted Colours - **Ink colour:** Assorted - **Material:** Plastic - **Model name:** 153528624 - **Point type:** Medium - **Special feature:** Liquid Ink - **Unit count:** 8.0 Count - **Writing instrument form:** Roller Ball Pen ## Images ![uni-ball Eye Designer UB-157D Liquid Ink Rollerball Pens - Pack of 8 - Image 1](https://m.media-amazon.com/images/I/81Nx3eEQEpL.jpg) ![uni-ball Eye Designer UB-157D Liquid Ink Rollerball Pens - Pack of 8 - Image 2](https://m.media-amazon.com/images/I/81-2kaUC4vL.jpg) ![uni-ball Eye Designer UB-157D Liquid Ink Rollerball Pens - Pack of 8 - Image 3](https://m.media-amazon.com/images/I/51Qu6FBIn5L.jpg) ![uni-ball Eye Designer UB-157D Liquid Ink Rollerball Pens - Pack of 8 - Image 4](https://m.media-amazon.com/images/I/718akLtkdFL.jpg) ![uni-ball Eye Designer UB-157D Liquid Ink Rollerball Pens - Pack of 8 - Image 5](https://m.media-amazon.com/images/I/71XgOibL8YL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: How fine are these I have 0.7 but it’s not really a fine script?** A: These are brilliant they are fine and brilliant colour i have bought more. **Q: does this type of pen work with spirograph** A: I'm sorry I don't know ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect pens. *by L***A on 21 August 2020* I LOVE these pens, really love them.
