This pen combines a high-capacity vacuum filling mechanism with a sleek, transparent design—advanced engineering at an accessible price.\u003cbr\u003e\u003cbr\u003eThe vacuum system is straightforward: twist the knob counter-clockwise, pull back the plunger, submerge the nib, and push down to create a vacuum that draws ink into the barrel. No cartridges or converters needed. An integrated ink shut-off valve seals the chamber when the knob is fully tightened, making it safe to carry on aeroplanes.\u003cbr\u003e\u003cbr\u003eThe updated valve design in this Vac700R improves ink flow when the knob is loosened compared to the original model. The transparent body showcases the pen's elegant mechanics and lets you monitor ink levels at a glance.\u003cbr\u003e\u003cbr\u003eTWSBI encourages hands-on ownership. Each pen ships with a wrench and silicone grease for long-term maintenance and disassembly. Take care when handling the fragile feed if you choose to take the nib apart—detailed instructions are included.\u003cbr\u003e\u003cbr\u003eRequires bottled ink, sold separately.","brand":"TWSBI","offers":[{"title":"Extra-Fine","offer_id":55284783677812,"sku":"4711467448132","price":149.0,"currency_code":"AUD","in_stock":true},{"title":"Fine","offer_id":55284789444980,"sku":"4711467448149","price":149.0,"currency_code":"AUD","in_stock":true},{"title":"Medium","offer_id":55284789477748,"sku":"4711467448156","price":149.0,"currency_code":"AUD","in_stock":true},{"title":"Broad","offer_id":55284789510516,"sku":"4711467448163","price":149.0,"currency_code":"AUD","in_stock":true},{"title":"1.1 Stub","offer_id":55284789543284,"sku":null,"price":149.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/2059\/3012\/files\/twsbi-700r-iris-fountain-pen-limited-edition-australia_1_f108732d-645b-4200-ac4b-f57d1c6f678c.webp?v=1788542287","url":"https:\/\/nibsternibs.com\/products\/twsbi-vac700r-fountain-pen-iris-stub","provider":"NibsterNibs","version":"1.0","type":"link"}
