Each pen comes with a standard international converter and will fit standard international short cartridges. \u003c\/p\u003e\n\u003cp\u003eThe Magna Carta Terrazzo Pink fountain pen is made of rare vintage casein resin, a material that you really don't see made in modern fountain pens. Casein is a thermoset bioplastic that was developed in the late 1800's before modern plastics and became popular for things like buttons, jewelry, and fountain pens in the early 1900's. Known also as \"milkstone\", it's a material derived from milk protein. It was popular at the time because of its ability to hold vibrant colors for a long time, and it doesn't have the same flammability risk that cellulose nitrate materials of the time had. If you're a fan of vintage \"celluloid\" pens and the warm feel and depth of color it has, casein has similar characteristics. This particular material is no longer made and will be available in extremely limited quantities. \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMATERIAL DISCLAIMER: \u003c\/strong\u003eThere are some tradeoffs to this material, however. Because of the way casein is derived and cured, the material remain hygroscopic, meaning it absorbs and releases moisture (much like wood does). Because of this, huge swings in humidity and exposure to water (including water-based ink) can cause the material to swell, warp, or even crack if exposed long enough. When inking the pen you'll want to wipe away any ink immediately, and absolutely do not eyedropper fill the pen, soak it for any period of time during cleaning, or leave it exposed to any type of moisture (a wet pocket, liquid on a tabletop, leaving it outside in the rain, etc). It should absolutely not be used in an ultrasonic cleaner under any circumstances. The solid pink cap itself is standard resin and not casein, it's just the rainbow material in the body, grip, and finials that are casein. Bottom line, this material is rare and special but also temperamental, so you should buy it knowing that it's not going to behave like other pen materials and should be handled with extra care and consideration. \u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eClick to shop all compatible \u003c\/span\u003e\u003ca href=\"https:\/\/www.gouletpens.com\/collections\/short-standard-international-cartridges\" title=\"Short Standard International Ink Cartridges\" target=\"_blank\"\u003eshort\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003estandard international ink cartridges.\u003c\/span\u003e\u003c\/p\u003e","brand":"Magna Carta","offers":[{"title":"14k Flex","offer_id":67598877720619,"sku":"MC-MCPCSN","price":460.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2603\/2528\/files\/MagnaCarta-TerrazzoPink-3_ac51d972-bab9-45b6-abd9-302999bc0617.jpg?v=1794432177","url":"https:\/\/www.gouletpens.com\/products\/magna-carta-terrazzo-pink-fountain-pen-limited-edition","provider":"The Goulet Pen Company","version":"1.0","type":"link"}
