{"product_id":"kaweco-al-sport-piston","title":"Kaweco Sport Fountain Pens \/ AL Sport Piston","description":"\u003cp\u003eThe modern Kaweco Sport resurrects a historic pocket pen first designed in 1911, and has become a classic pocket pen in its own right. Measuring only 10.5cm when closed, the pen expands to a full 13.5 posted, thus Kaweco’s tagline “Small in the pocket, great in the hand.” The threaded cap will stay securely closed for pocket carry.\u003c\/p\u003e\u003cp\u003eThis particular Kaweco Sport Piston Filler adopts the aluminum construction of the AL Sport line, and adds not only a piston filling system but an ink window and integrated clip, all of which add a cool vintage touch to the pen. The blind cap unscrews to reveal the piston mechanism, which is turned to work the piston and fill the pen with ink. As of October 2025, the AL Sport Piston Filler is also available in a Navy Blue Color!\u003c\/p\u003e\u003cp\u003e\u003ca href=\"\/products\/kaweco-bottled-fountain-pen-ink\"\u003eBottled ink sold separately\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eMade in Germany.\u003c\/p\u003e","brand":"Kaweco","offers":[{"title":"Navy Blue \/ Extra Fine","offer_id":48896759496857,"sku":"SQ8869372","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Navy Blue \/ Broad","offer_id":48896759431321,"sku":"SQ0784972","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Navy Blue \/ Double Broad","offer_id":48896759464089,"sku":"SQ2973045","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Navy Blue \/ Fine","offer_id":48896759529625,"sku":"SQ4043582","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Navy Blue \/ Medium","offer_id":48896759562393,"sku":"SQ0512010","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ Extra Fine","offer_id":48896759267481,"sku":"SQ7623381","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Broad","offer_id":48896759300249,"sku":"SQ6104143","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Double Broad","offer_id":48896759333017,"sku":"SQ5471687","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ Fine","offer_id":48896759365785,"sku":"SQ6210093","price":190.0,"currency_code":"USD","in_stock":false},{"title":"Black \/ Medium","offer_id":48896759398553,"sku":"SQ0851933","price":190.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/4239\/9641\/files\/IMG_6742.webp?v=1787035690","url":"https:\/\/shop.gentlemanstationer.com\/products\/kaweco-al-sport-piston","provider":"The Gentleman Stationer","version":"1.0","type":"link"}
