Review: NOT 10 pieces - The listing is for 10 pieces but I received 1 only. For the price, this is a rip off. Review: Very great value for money compared to other places that sell these refills. My only complaint with Uniball One Gel refill is that I wish there was more ink in each refill so that the pen can last longer. As someone who writes a lot for school, I find myself going through each refill extremely fast. Fortunately, the writing experience makes up for it. ## Features - Series: Uni-ball one - Features: Black is darker and the colors are more vibrant, making it easy to remember and write crisp letters - Design: The shaft design has a simple and straight shape, and the oval shaped open wire clip makes it easy to clip in your notebook or notebook - Lead diameter: 0.01 inch (0.38 mm); Ink color: Yellow - Size: Shaft Diameter 0.4 x Thickness 0.6 x Total Length 5.5 inches (10.5 x 15.0 x 139.5 mm); Weight: 3.9 oz (109.4 g) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08665WBBT | | Best Sellers Rank | #12,312 in Office Products ( See Top 100 in Office Products ) #1,279 in Gel Ink Rollerball Pens | | Brand | 三菱鉛筆 | | Closure | Retractable | | Color | Yellow | | Customer Reviews | 4.6 4.6 out of 5 stars (776) | | Date First Available | 29 August 2023 | | Grip Type | plastic | | Ink Color | Yellow | | Item Weight | 110 g | | Line Size | 0.38mm | | Manufacturer | 三菱鉛筆 | | Manufacturer Part Number | ハコUMNS38.2 | | Material Type | Plastic | | Model number | ハコUMNS38.2 | | Number of Items | 10 | | Pencil Lead Degree (Hardness) | Hard | | Point Type | ball tip | | Product Dimensions | 13.95 x 1.05 x 1.5 cm; 110 g | | Size | 1 Count (Pack of 10) | ## Product Details - **Brand:** 三菱鉛筆 - **Colour:** Yellow - **Ink colour:** Yellow - **Material:** Plastic - **Writing instrument form:** Roller Ball Pen ## Images ![Mitsubishi Pencil Uni-Ball One UMNS38.2 Gel Ballpoint Pens, 0.01 inches (0.38 mm), Yellow, 10 Pieces - Image 1](https://m.media-amazon.com/images/I/61OEe9Nau6L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐ NOT 10 pieces *by L***I on 24 November 2024* The listing is for 10 pieces but I received 1 only.
