{"product_id":"robert-oster-evening-sapphire-signature-ink","title":"Robert Oster Evening Sapphire Signature Ink","description":"\u003cp\u003eRobert Oster Evening Sapphire Signature Ink is a muted, dusky blue fountain pen ink with soft gray undertones. Rather than a bright, highly saturated sapphire, it has a calm evening-blue character that can move from lighter blue-gray tones to deeper blue as more ink is applied. Made in Australia, it is part of the Robert Oster Signature range.\u003c\/p\u003e\n\u003cp\u003eThe ink offers medium shading, allowing natural variation between lighter and darker strokes. In wetter applications and larger swatches, a subtle pink sheen can appear around the edges, adding an understated contrast to the blue base. The effect is especially noticeable on fountain-pen-friendly papers and with wetter nibs.\u003c\/p\u003e\n\u003cp\u003eEvening Sapphire comes in a 50ml bottle and is designed for fountain pen use. Its balanced blue-gray character makes it a versatile choice for everyday writing, journaling, correspondence, note-taking, and creative work, especially when you want a blue that feels softer and more atmospheric than a standard bright blue.\u003cbr\u003e\u003c\/p\u003e","brand":"Robert Oster","offers":[{"title":"4ml(Sample)","offer_id":54597245862198,"sku":"55044S","price":3.75,"currency_code":"USD","in_stock":false},{"title":"50ml","offer_id":54597245894966,"sku":"55044","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-E-9.webp?v=1789838619","url":"https:\/\/writelovepens.com\/products\/robert-oster-evening-sapphire-signature-ink","provider":"Write Love","version":"1.0","type":"link"}
