Created as part of the collaboration between Robert Oster and Joshua Thorp, it reflects the collection’s focus on colors that carry a sense of place and mood. \u003c\/p\u003e\n\u003cp\u003eOn paper, it appears as a deep purple with blue undertones that can shift depending on the pen and ink flow. In finer writing, it can look more subdued and slightly indigo, while wetter strokes bring out a brighter, more saturated violet. The ink shows noticeable shading, moving between lighter lavender tones and deeper purple areas within the same word, which gives writing a layered and expressive feel rather than a uniform line. \u003c\/p\u003e\n\u003cp\u003eIn everyday use, it flows smoothly and performs well in fountain pens, making it suitable for journaling, notes, and creative writing. Like most inks in this range, it is not water-resistant, so it can fade if exposed to moisture, but on good paper it maintains a strong, elegant color with a slightly artistic edge.\u003c\/p\u003e","brand":"Robert Oster","offers":[{"title":"4ml(Sample)","offer_id":53913490456886,"sku":"55055S","price":3.75,"currency_code":"USD","in_stock":false},{"title":"50ml","offer_id":53913490489654,"sku":"55055","price":19.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/2840\/4022\/files\/WhatsAppImage2026-01-19at1.04.53PM.webp?v=1776324031","url":"https:\/\/writelovepens.com\/products\/robert-oster-x-joshua-thorp-fountain-pen-ink-jacaranda-jewel","provider":"Write Love","version":"1.0","type":"link"}
