{"product_id":"twsbi-vac-700r-kyanite","title":"TWSBI Vac 700R Fountain Pen \/ Kyanite","description":"\u003cp\u003eTWSBI’s vacuum-filler has been reworked to ensure more consistent ink flow when the valve is opened, and it’s now available in the unique “Iris” and “Kyanite” finishes in addition to standard clear demonstrator options. To fill a vacuum-filler fountain pen, simply retract the plunger, submerge the nib section into your ink bottle, and depress the plunger to watch the pen fill. This style of pen can be perfect for those who travel, since the pen includes a “shut-off valve” to prevent spills and leakage. (Note that with the “Iris” pens, no two finishes will be exactly alike.)\u003c\/p\u003e\u003cp\u003eAvailable in multiple nib sizes, including extra fine, fine, medium, broad, and 1.1mm stub. \u003ca href=\"\/collections\/bottled-ink\"\u003eFountain pen ink is sold separately\u003c\/a\u003e, and this pen uses bottled ink only (no cartridges).\u003c\/p\u003e","brand":"TWSBI","offers":[{"title":"Extra Fine","offer_id":48896928317593,"sku":"SQ6564225","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Fine","offer_id":48896928350361,"sku":"SQ4068616","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Medium","offer_id":48896928383129,"sku":"SQ0477281","price":88.99,"currency_code":"USD","in_stock":false},{"title":"Broad","offer_id":48896928415897,"sku":"SQ1232456","price":88.99,"currency_code":"USD","in_stock":true},{"title":"1.1mm Stub","offer_id":48896928448665,"sku":"SQ7625847","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/4239\/9641\/files\/Image_1_5861a6c6-dc7b-4727-a635-306713a68532.webp?v=1787036554","url":"https:\/\/shop.gentlemanstationer.com\/products\/twsbi-vac-700r-kyanite","provider":"The Gentleman Stationer","version":"1.0","type":"link"}
