At the core of the formula is a POA (polyoxyalkylene) surfactant — a molecular layer that sits between the writing ball and the paper surface, reducing friction by approximately 40% compared to conventional water-based rollerball refills. The result is a writing feel that is noticeably softer and smoother without sacrificing control or line precision.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe ink is water-based and pigment-based, which gives it a different character from most gel refills. The pigment particles settle on the paper surface rather than seeping into the fibres, producing a high-contrast black line with good resistance to water and light once dry. Attracting particles in the formula also draw the ink together as it lands on the page, minimising feathering and bleed-through — even on thinner papers. It dries quickly enough to be practical for left-handed writers.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe refill is designed specifically for the uni-ball ZENTO range and is compatible with the ZENTO Standard, Flow, and Signature models. Features\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eZENTO ink with POA surfactant — approx. 40% less friction than conventional water-based rollerballs\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eWater-based pigment formula — rich, high-contrast black line\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eAttracting particles minimise feathering and bleed-through for crisp, clean lines\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eQuick-drying — suitable for left-handed writers\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCompatible with uni-ball ZENTO Standard, Flow, and Signature models\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTip size: 0.5 mm\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eMade in Japan\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca title=\"Mitsubishi Uni items\" href=\"https:\/\/shopnoteworthy.ca\/collections\/mitsubishi\"\u003eSee all Mitsubishi - uni items\u003c\/a\u003e\u003c\/p\u003e","brand":"SD-BUNGU","offers":[{"title":"Default Title","offer_id":43168662061123,"sku":"MI-UBRZ05-BL","price":3.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2976\/4338\/files\/UniZentoRefill_05Blue.jpg?v=1776798442","url":"https:\/\/shopnoteworthy.com\/products\/mitsubishi-uni-ball-zento-refill-blue-0-5-mm-copy","provider":"Noteworthy Stationery","version":"1.0","type":"link"}
