The translucent barrel lets you watch your ink levels at a glance, so you'll never be caught dry.\u003c\/p\u003e\n\u003cp\u003eThe real magic is in the mix of materials: glossy resin paired with matte ebonite creates a tactile experience that feels premium in hand, while the subtle mottled pattern gives it an understated, granite-like character. \u003c\/p\u003e\n\u003cp\u003eFitted with a #6 steel Jowo nib, it fills via eyedropper mechanism with impressive ink capacity. The clever valve lets you write freely during long sessions, then seal it shut for travel without worry.\u003c\/p\u003e\n\u003cp\u003eThis is an eyedropper pen—a filling system that's uncommon in modern pens but brilliantly practical. You fill it using the included pipette, drawing ink directly into the barrel.\u003c\/p\u003e\n\u003cp\u003eThe built-in valve seals the ink supply above the nib, making it safer to carry and preventing leakage during travel. It also stops the pen from burping ink when your hand warms it up.\u003c\/p\u003e\n\u003cp\u003eIn practice, it's simple: unscrew the valve slightly before a long writing session, tighten it when you're done. For quick notes, the ink already in the feed is ready to go. Opus 88 has perfected this Japanese-style filling method—it's their signature.\u003c\/p\u003e\n\u003cp\u003eComes gift boxed.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eeye dropper filling system\u003c\/li\u003e\n\u003cli\u003epipette included\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003e #6 steel Jowo nib\u003c\/li\u003e\n\u003cli\u003eGift boxed\u003c\/li\u003e\n\u003cli\u003eMade in Taiwan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAbout Opus 88\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOpus 88 is a highly respected Taiwanese fountain pen brand that has carved out a distinct niche in the stationery world; t\u003cspan class=\"citation-38 citation-end-38\"\u003ehey are the modern masters of the \"Japanese-style\" eyedropper pen.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/hunterpaperco.com\/collections\/opus-88\" target=\"_blank\"\u003e\u003cspan class=\"citation-38 citation-end-38\"\u003eView all Opus 88 pens we stock\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Opus 88","offers":[{"title":"Extra Fine","offer_id":56752133669250,"sku":null,"price":85.0,"currency_code":"GBP","in_stock":false},{"title":"Fine","offer_id":56752133702018,"sku":null,"price":85.0,"currency_code":"GBP","in_stock":true},{"title":"Medium","offer_id":56752133734786,"sku":null,"price":85.0,"currency_code":"GBP","in_stock":false},{"title":"Broad","offer_id":56752133767554,"sku":null,"price":85.0,"currency_code":"GBP","in_stock":true},{"title":"1.4mm Stub","offer_id":56752133800322,"sku":null,"price":85.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0274\/0427\/1699\/files\/OP66009-ZZZ_Opus-88-Koloro-Eye-Dropper-Fountain-Pen-Teal_P1.webp?v=1783422267","url":"https:\/\/hunterpaperco.com\/products\/opus-88-koloro-teal-eyedropper-fountain-pen","provider":"Hunter Paper Co.
