It is dark enough for long-form writing, but the violet undertone keeps the page from feeling flat or ordinary.\u003c\/p\u003e\u003cp\u003eReview testing shows medium-low shading and only a trace of reddish sheen, usually in heavier pooling rather than across ordinary lines. It is therefore better understood as a dark violet writing ink than as a showy sheen ink. On fountain-pen-friendly paper, broader and wetter nibs reveal more of the purple beneath the near-black surface.\u003c\/p\u003e\u003ch3\u003eInk character\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e deep black-violet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShading:\u003c\/strong\u003e low to medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSheen:\u003c\/strong\u003e very slight reddish sheen in pooled areas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShimmer:\u003c\/strong\u003e none\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow:\u003c\/strong\u003e moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater resistance:\u003c\/strong\u003e low\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest suited to:\u003c\/strong\u003e everyday writing, notes, correspondence\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBlack Violet is useful when black feels too severe and bright purple feels too conspicuous: a quiet, serious ink with just enough color to reward a closer look.\u003c\/p\u003e","brand":"Robert Oster","offers":[{"title":"50 mL","offer_id":49127014924513,"sku":"RO-50510-50ML","price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/8486\/6785\/files\/robert-oster-black-violet-fountain-pen-ink-swatch.png?v=1789523168","url":"https:\/\/bostonlore.com\/products\/robert-oster-black-violet-50ml-fountain-pen-ink","provider":"Boston Lore Studio","version":"1.0","type":"link"}
