By fusing the traditional mechanisms of the fountain pen with a modern industrial design, TWSBI has created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present. The Diamond 580 comes with all detachable parts, as TWSBI felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen (though no disassembly is required to completely enjoy your TWSBI). \u003cstrong\u003ePlease note that the pen does not ship with ink, but \u003c\/strong\u003e\u003ca href=\"\/collections\/bottled-ink\"\u003e\u003cstrong\u003eink can be purchased separately here\u003c\/strong\u003e\u003c\/a\u003e\u003cstrong\u003e.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe idea behind the TWSBI Diamond 580 and its predecessors, the 540 and 530, was to go back to basics and capture the simplicity and elegance of traditional writing instruments. In recent years, the development and modernization of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity. It was our goal to bring the past back to life by creating a traditional fountain pen that even modern day society can appreciate.\u003c\/p\u003e","brand":"TWSBI","offers":[{"title":"Extra Fine","offer_id":48896912687257,"sku":"SQ5564251","price":72.99,"currency_code":"USD","in_stock":false},{"title":"Fine","offer_id":48896912720025,"sku":"SQ0275604","price":72.99,"currency_code":"USD","in_stock":false},{"title":"Medium","offer_id":48896912752793,"sku":"SQ0408354","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Broad","offer_id":48896912785561,"sku":"SQ5120854","price":72.99,"currency_code":"USD","in_stock":true},{"title":"1.1mm Stub","offer_id":48896912818329,"sku":"SQ2603125","price":72.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/4239\/9641\/files\/prussian2_1024x1024_73a73b92-e43a-4da9-830a-f295002dd154.webp?v=1788799607","url":"https:\/\/shop.gentlemanstationer.com\/products\/twsbi-580-alr-prussian-blue-fountain-pen","provider":"The Gentleman Stationer","version":"1.0","type":"link"}
