{"product_id":"twsbi-classic-sapphire-fountain-pen","title":"TWSBI Classic Sapphire Fountain Pen","description":"\u003cp\u003eThe TWSBI Classic is highly appealing in both form and function. It is slightly slimmer than the Diamond 580  and is available in three finishes: black, blue or burgundy. It's high-capacity piston filling mechanism is easily operated by twisting the knob at the end of the barrel counter-clockwise to extend the piston, submerging the nib in ink, then screwing the knob tight to retract the piston, drawing ink into the pen straight from the bottle.\u003c\/p\u003e\n\u003cp\u003eIt has a transparent ink window in the grip section to gage ink levels and two o-rings on the piston knob for posting the cap securely. Since it has a piston fill mechanism, it can only be filled using an ink bottle.\u003c\/p\u003e\n\u003cp\u003eIt comes with a wrench and a vial of silicone grease you can use for at-home maintenance. This pen may come with ink residue in the nib from being dip tested by TWSBI at the factory. As with all new fountain pens, we recommend giving your TWSBI a good cleaning before you use it.\u003c\/p\u003e\n\u003cp\u003eTWSBI Classic Sapphire Fountain Pen Features:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePen Material: Resin and Aluminum\u003c\/li\u003e\n\u003cli\u003eNib Material: Stainless Steel\u003c\/li\u003e\n\u003cli\u003eCap: Postable\u003c\/li\u003e\n\u003cli\u003eFilling Mechanism: Internal Piston-Fill Mechanism\u003c\/li\u003e\n\u003cli\u003eCompatible Refills: Bottled Inks\u003c\/li\u003e\n\u003cli\u003ePen Length, Closed: 5.39 in. \/ 137mm\u003c\/li\u003e\n\u003cli\u003ePen Length, Open (Cap Off): 5.12 in. \/ 130mm\u003c\/li\u003e\n\u003cli\u003ePen Length, Open (Cap Posted): 6.42 in. \/163mm\u003c\/li\u003e\n\u003cli\u003ePen Max Diameter, Barrel: 0.5 in. \/ 13mm\u003c\/li\u003e\n\u003cli\u003ePen Diameter, Grip: 0.36 in. \/ 10mm\u003c\/li\u003e\n\u003cli\u003eTotal Weight: .56oz. \/ 16g\u003c\/li\u003e\n\u003cli\u003eMax Ink Capacity: 1.50ml\u003c\/li\u003e\n\u003cli\u003ePackaged in clear case with a wrench and silicone grease.\u003c\/li\u003e\n\u003cli\u003eMade in Taiwan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\u003c\/div\u003e","brand":"TWSBI Pens","offers":[{"title":"Medium","offer_id":34486537846923,"sku":"M7443720","price":50.0,"currency_code":"USD","in_stock":false},{"title":"Fine","offer_id":34486537879691,"sku":"M7443680","price":50.0,"currency_code":"USD","in_stock":false},{"title":"Extra Fine","offer_id":34486537912459,"sku":"M7443640","price":50.0,"currency_code":"USD","in_stock":false},{"title":"Broad","offer_id":34486537945227,"sku":"M7443760","price":50.0,"currency_code":"USD","in_stock":false},{"title":"1.1mm Stub","offer_id":34486537977995,"sku":"M7443800","price":50.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1693\/8459\/products\/twsbi-classic-sapphire-fountain-pen-681.jpg?v=1762202146","url":"https:\/\/goldspot.mom\/products\/twsbi-classic-sapphire-fountain-pen","provider":"Goldspot Pens","version":"1.0","type":"link"}
