Thanks to PW Akkerman they allowed us to stock a few pieces.\nDescription\n\n\nFollowing the success of our 'Akkerman Orange' and 'Blue Eclipse' fountain pens and the positive, enthusiastic response we received on them, we collaborated with Kaweco once more this year to create a new 'Akkerman Amsterdam exclusive' Kaweco fountain pen. This resulted in a new Kaweco AL Sport, named 'Blue Lagoon'!\nThe pen is named after the lake of the same name in Iceland, which the pen's colors remind us of. The pen has a beautiful dark pastel blue color with a matte finish. The pen is then finished with a black nib and black decal, matching our previous editions. 'Akkerman Amsterdam' is subtly readable in the cap of the pen.\nThe Kaweco AL Sport Akkerman Amsterdam 'Blue Lagoon' fountain pen is available exclusively at our store and has a limited availability. The pen is available in  F, M, B and BB - while stocks last of each nib, of course.\n\n\n\n\nAbout Kaweco\nThe Kaweco ethos is one of producing high-quality fountain pens at affordable prices. The German-based company has a long history – over 130 years – of producing excellent writing implements. Today much of its range is based on vintage designs using modern materials.\nSpecs\n\n\n\n\nPen Material: Aluminium\nNib Material: Black Coated - steel with plastic feed (no. 5)\nFilling Mechanism: Cartridge (standard international, included) or Converter (not included, Kaweco Sport Converter - proprietary), eyedropper convertible\nPen Length (closed): 4.17 in . / 106mm\nPen Length (open, cap off): 3.94 in . / 100mm\nPen Length (open, cap posted): 5.27 in. / 134mm\nPen Diameter (cap): 0.51 in. / 13mm\nPen Diameter (grip section): 0.35 in. / 9mm\nPen Weight: 0.3oz / 8.5g\nPackaged in a metal tin gift box\n\n","images":["https://cdn.shopify.com/s/files/1/0575/7177/files/Kaweco-AL-Sport-Akkerman-Blue-Lagoon-Fountain-Pen-2.jpg?v=1757660881","https://cdn.shopify.com/s/files/1/0575/7177/files/Kaweco-AL-Sport-Akkerman-Blue-Lagoon-Fountain-Pen.jpg?v=1757660881","https://cdn.shopify.com/s/files/1/0575/7177/files/Kaweco-AL-Sport-Akkerman-Blue-Lagoon-Fountain-Pen-3.jpg?v=1709904760","https://cdn.shopify.com/s/files/1/0575/7177/files/Kaweco-AL-Sport-Akkerman-Blue-Lagoon-Fountain-Pen-4.jpg?v=1709904765","https://cdn.shopify.com/s/files/1/0575/7177/files/Kaweco-AL-Sport-Akkerman-Blue-Lagoon-Fountain-Pen-5.jpg?v=1709904769"],"price":149,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:00.820Z"},"share_url":"https://firestarter.network/l/lst_fePqgN_l","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
