{"product_id":"robert-oster-australian-australian-opal-grey-signature-ink","title":"Robert Oster Australian Opal Grey Signature Ink","description":"\u003cp\u003eRobert Oster Australian Opal Grey is a soft, pale grey fountain pen ink with a subtle purple undertone that gives the color more depth than a traditional neutral grey. Made in Australia, it has a restrained and sophisticated appearance that can shift gently with different nib widths and ink application, making it an interesting choice for everyday writing and more expressive work.\u003c\/p\u003e\n\u003cp\u003eThe ink offers medium shading, allowing lighter and darker areas to appear naturally across the page. In heavier applications, a small touch of copper sheen can also become visible, while the ink itself contains no shimmer. Its flow is on the drier side, so it can perform particularly well in wetter-writing fountain pens, with the subtle color variation becoming more noticeable on fountain-pen-friendly papers.\u003c\/p\u003e\n\u003cp\u003eAustralian Opal Grey comes in a 50ml bottle as part of the Robert Oster Signature ink range. The ink is non-pigmented and not water-resistant, making it best suited to everyday writing, journaling, note-taking, correspondence, and creative work where its understated grey-purple character can be appreciated. The bottle is made from recycled PET plastic, reflecting Robert Oster’s Australian approach to producing its fountain pen inks.\u003cbr\u003e\u003c\/p\u003e","brand":"Robert Oster","offers":[{"title":"4ml(Sample)","offer_id":54596979720502,"sku":"50281S","price":3.75,"currency_code":"USD","in_stock":false},{"title":"50ml","offer_id":54596979753270,"sku":"50281","price":18.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/2840\/4022\/files\/Robert-Oster-Fountain-Pen-Ink-Signature-A-33.webp?v=1789834732","url":"https:\/\/writelovepens.com\/products\/robert-oster-australian-australian-opal-grey-signature-ink","provider":"Write Love","version":"1.0","type":"link"}
