{"product_id":"uni-ball-eye-ultra-micro-rollerball-pen-0-38-mm","title":"Uni-Ball Eye Ultra Micro Rollerball Pen 0.38 mm","description":"The Eye Ultra Micro uses a 0.38 mm tip, the thinnest in the Eye liquid ink line, putting down a needle-sharp line around 0.2 mm wide — fine enough for dense tracking grids or detailed entries where a standard 0.5 mm tip would already feel too thick. Most pens get scratchy or start skipping at this small a tip size, but the Uni-Flow capillary regulator keeps ink pressure steady through the barrel, so the line stays smooth rather than catching on the paper.\u003cbr\u003e\u003cbr\u003eThe ink is uni-ball's \"Super Ink,\" bonding chemically into paper fibers so it dries waterproof, fade-proof, and certified tamper-resistant under ISO 14145-2 — and at this fine a width, it also resists feathering or ghosting through to the back of thinner notebook pages.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eTip: 0.38 mm tungsten carbide rollerball\u003c\/li\u003e\n\u003cli\u003eLine width: approx. 0.2 mm\u003c\/li\u003e\n\u003cli\u003eInk: uni Super Ink, water-based pigment, waterproof, fade-proof, tamper-resistant, ISO 14145-2\u003c\/li\u003e\n\u003cli\u003eDelivery: Uni-Flow regulator system, visible ink window\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cstrong\u003eAvailable colors:\u003c\/strong\u003e Black, Blue, Red","brand":"Uni Mitsubishi","offers":[{"title":"Black","offer_id":51779163881821,"sku":"4902778184998","price":800.0,"currency_code":"JPY","in_stock":true},{"title":"Red","offer_id":51779163947357,"sku":"4902778185018","price":800.0,"currency_code":"JPY","in_stock":true},{"title":"Blue","offer_id":51779163980125,"sku":"4902778185001","price":800.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4405\/4621\/files\/uni-ball-eye-ultra-micro-rollerball-pen-0.38-mm_4902778184998_cc.jpg?v=1718381781","url":"https:\/\/unfide.com\/da\/products\/uni-ball-eye-ultra-micro-rollerball-pen-0-38-mm","provider":"UNFADE","version":"1.0","type":"link"}
