{"product_id":"twsbi-vac-700r-fountain-pen-clear","title":"TWSBI Vac 700R Fountain Pen - Clear","description":"The TWSBI Vac 700R combines engineering precision with visual appeal. This fountain pen features a vacuum filling mechanism that draws ink directly from a bottle—no cartridges needed. Simply twist the knob counter-clockwise, pull the plunger, submerge the nib, and push down to create the vacuum that fills the barrel.\u003cbr\u003e\u003cbr\u003eThe transparent body showcases the pen's inner mechanics while the ink shut-off valve prevents leaks during travel—twist the knob fully closed before flying. The updated valve design in this model improves ink flow when loosened, refining the original Vac 700 experience.\u003cbr\u003e\u003cbr\u003eBuilt for hands-on ownership, the Vac 700R arrives with a wrench and silicone grease for long-term maintenance and disassembly. The nib and feed are delicate; follow included instructions carefully if you choose to take the pen apart.\u003cbr\u003e\u003cbr\u003eRequires bottled fountain pen ink, sold separately.","brand":"TWSBI","offers":[{"title":"Extra-Fine","offer_id":55284783645044,"sku":"4711467445957","price":129.0,"currency_code":"AUD","in_stock":true},{"title":"Fine","offer_id":55284790526324,"sku":"4711467445964","price":129.0,"currency_code":"AUD","in_stock":true},{"title":"Medium","offer_id":55284790559092,"sku":"4711467445971","price":129.0,"currency_code":"AUD","in_stock":true},{"title":"Broad","offer_id":55284790591860,"sku":"4711467445988","price":129.0,"currency_code":"AUD","in_stock":true},{"title":"1.1 Stub","offer_id":55284790624628,"sku":"4711467445995","price":129.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/2059\/3012\/files\/9c1c61a6-8b88-4663-a09c-14ded3b86819_1a1fefdb-9396-4f98-91db-983e053c5911.webp?v=1788542283","url":"https:\/\/nibsternibs.com\/products\/twsbi-vac-700r-fountain-pen-clear","provider":"NibsterNibs","version":"1.0","type":"link"}
