{"product_id":"uni-ball-um-153s-gel-impact-0-1-roller-ball-pen","title":"Uni Ball UM-153S Gel Impact 0.1 Roller Ball Pen","description":"The Signo Gel Impact uses a 1.0 mm tungsten carbide tip, broad enough to glide across the page with minimal drag rather than scratching the way a finer rollerball tip can. The ink is uni-ball's gel formula with \"Super Ink\" technology, which bonds chemically into the paper fibers rather than sitting on the surface — that's what makes the line water-resistant, fade-resistant, and difficult to alter or erase once it's dry, a relevant point for anything that needs to hold up as a permanent, tamper-resistant record.\u003cbr\u003e\u003cbr\u003eBecause the cured ink resists water, it can also be safely worked over with wet media afterward — water-based markers, glazes, or watercolor washes — without the underlying line bleeding or lifting. The barrel is gunmetal grey with a rubberized grip section, and the tip section unscrews to take standard uni-ball UMR-10 refills rather than needing to be thrown away once empty.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eTip: 1.0 mm broad tungsten carbide rollerball\u003c\/li\u003e\n\u003cli\u003eInk: water-based gel with uni Super Ink, water-resistant, fade-resistant\u003c\/li\u003e\n\u003cli\u003eBody: gunmetal grey, rubberized grip\u003c\/li\u003e\n\u003cli\u003eRefill: compatible with uni-ball UMR-10 cartridges\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":51780549050717,"sku":"4902778744772","price":700.0,"currency_code":"JPY","in_stock":false},{"title":"Red","offer_id":51780549083485,"sku":"4902778744796","price":700.0,"currency_code":"JPY","in_stock":true},{"title":"Blue","offer_id":51780549116253,"sku":"4902778744789","price":700.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4405\/4621\/files\/uni-ball-um-153s-gel-impact-0.1-roller-ball-pen_cc.jpg?v=1718387779","url":"https:\/\/unfide.com\/sv\/products\/uni-ball-um-153s-gel-impact-0-1-roller-ball-pen","provider":"UNFADE","version":"1.0","type":"link"}
