## Description

Product Description Mitsubishi Pencil from Shingawa, Tokyo, Japan has been working since 1887 to improve the quality of its products and enhance its technologies. This is the writing instrument manufacturers to take environmental issues into consideration, launching products with recycled materials in 1992. Specification uni-ball products are developed through technical expertise accumulated over the years include “uni-ball” water based ink roller balls with metal tips. An established product with reliable features. The “UNI-FLOW SYSTEM” ensures a continuous write with the same thickness to the very last drop of ink. Know the Technology Water Resistant: Dyestuff Ink particle is easily soluble in water and will bleed on the paper, uni super ink – pigmented ink will bond itself to the paper fibers once it is settled, it is not soluble in water. Light Resistant: The size of uni super ink particle is larger than dyestuff Ink. Therefore its surface is less affected and the colour remains vivid. Time Resistant: Difference between structure of molecules. Molecules of dye ink break down because of the sunlight and air but uni Super ink is difficult to break down. Structure of the UNI-FLOW SYSTEM The “UNI-FLOW SYSTEM” ensures smooth writing performance to the last drop of ink. Excess ink flow from the ink reservoir can be temporarily stored to ensure constant ink flow to the pen point. Quick drying and smooth ink flow system mean your documents remain smudge free. Durable Needle Tip Produces a thin and precise line. Constantly sharp pen line is maintained from first stroke to last. Features a durable pressure-resistant tip that won't bend or break even under strong pen pressure. Safety Cap A cap design that eliminates the possibility of children swallowing and choking with the cap. Despite the vent hole, the cap firmly covers the tip when closed and prevents the tip from drying.

Review: Japanese quality never fails to impress! - 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!
