{"type":"firestarter.listing","listing":{"id":"lst_uiObYrQg","product_name":"Diamine Zeugma Türkiye Exclusive Ink - Extreme Sheen","category":"Fountain Pen Ink","description":"Diamine Zeugma is a very special fountain pen ink developed by Diamine in 2025 exclusively for Türkiye, and introduced worldwide for the first time as part of the Extreme Sheen category. Although it contains no shimmer particles, Zeugma displays an exceptionally rich and dynamic color character across different paper types. When first applied, the ink resembles deep red wine tones; as it dries and the viewing angle changes, green-leaning reflective highlights begin to appear on the surface. This color shift adds depth, vibrancy, and a striking visual presence to your writing.\nThanks to its Extreme Sheen formulation, the effect becomes most pronounced on high-quality, well-coated papers with good sheen performance. On low-absorbency and smooth surfaces, the ink remains on the paper longer, delivering a strong and glossy sheen. Since it is shimmer-free, it can be used comfortably even with EF and F nibs, without flow issues or clogging.\n\n\n\nBrand\nDiamine\n\n\nType\nBottled Ink\n\n\nName\nZeugma\n\n\nColor\nGreen\n\n\nShading\nShading\n\n\nSheen\nSheen\n\n\nShimmer\nShimmer\n\n\nDry Time\n35 Seconds\n\n\nBottle Material\nGlass\n\n\nBottle Opening Diameter\n18mm\n\n\nVolume\n30 Ml\n\n\nOrigin\nEngland\n\n\n\nInk colors give different results on different papers.
