{"product_id":"on-the-run-otr-988-ball-pen-fluid-100-ml","title":"On The Run OTR.988 Ball Pen Fluid 100 ml","description":"OTR.988 Ball Pen Fluid is a highly concentrated alcohol-based ink gel designed for mixing, not for direct use. It's thick, heavily pigmented, and built to be added to existing inks or paints to deepen color intensity, boost opacity, and increase pigment saturation. Comes in multiple colors including black, blue, red, green, and violet.\u003cbr\u003e\u003cbr\u003eWriters and artists use this to create custom ink blends - stronger, darker, richer than standard inks. Mix it into alcohol-based inks, correction fluid (for pastel shades), marker inks, or paint formulas. Typically add no more than about 10% Ball Pen Fluid to avoid slowing drying times or altering flow too much. It makes inks harder to buff and increases gloss.\u003cbr\u003e\u003cbr\u003e100ml bottle. Don't use it straight in markers - it's too thick to flow through marker mechanisms on its own. This is a concentrate for DIY marker refills, boosting existing inks, or experimenting with custom color blends. More economical and consistent than breaking open disposable pens for ink extraction. For writers who want control over their ink performance and permanence.","brand":"On The Run","offers":[{"title":"Black","offer_id":51782341951837,"sku":"4260737398191","price":1600.0,"currency_code":"JPY","in_stock":false},{"title":"Red","offer_id":51782341984605,"sku":"4260737398276","price":1600.0,"currency_code":"JPY","in_stock":true},{"title":"Violet","offer_id":51782342017373,"sku":"4260737398481","price":1600.0,"currency_code":"JPY","in_stock":false},{"title":"Blue","offer_id":51782342050141,"sku":"4260737398252","price":1600.0,"currency_code":"JPY","in_stock":false},{"title":"Green","offer_id":51782342082909,"sku":"4260737398467","price":1600.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4405\/4621\/files\/on-the-run-otr.988-ball-pen-fluid-100-ml_cc_eb7119df-ca3a-4d6a-9588-3986095f40d1.jpg?v=1718396792","url":"https:\/\/unfide.com\/products\/on-the-run-otr-988-ball-pen-fluid-100-ml","provider":"UNFADE","version":"1.0","type":"link"}
