{"product_id":"tombow-fudenosuke-twin-brush-pen-blackgrey","title":"Tombow Fudenosuke Twin Brush Pen, Black\/Grey","description":"This pen puts two separate ink reservoirs in one barrel — solid black on one end, a softer transparent grey on the other — both running through Tombow's firm elastomer brush tip rather than a floppy felt tip, so the line stays controllable even for someone who hasn't practiced brush lettering. The two-tone setup is built around a specific bullet journal technique: write a header or block in black, then switch ends and add a grey shadow line just below or beside it for a quick faux-3D drop shadow effect, without needing a second pen.\u003cbr\u003e\u003cbr\u003eThe ink is a water-based pigment formula that dries water-resistant and smudge-proof, so it can be highlighted over later without smearing or bleeding into the highlighter color.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eTips: twin elastic elastomer brush tips, fine to medium line width\u003c\/li\u003e\n\u003cli\u003eInk: black on one end, transparent grey on the other\u003c\/li\u003e\n\u003cli\u003eInk technology: water-based pigment, odorless, water-resistant once dry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tombow","offers":[{"title":"Default Title","offer_id":51784858239325,"sku":"4901991645873","price":900.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0873\/4405\/4621\/files\/Tombow-Fudenosuke-Twin-Brush-Pen-BlackGrey_All_786_5.jpg?v=1718410652","url":"https:\/\/unfide.com\/da\/products\/tombow-fudenosuke-twin-brush-pen-blackgrey","provider":"UNFADE","version":"1.0","type":"link"}
