{"type":"firestarter.listing","listing":{"id":"lst_-PT5cjLV","product_name":"The BiFrost","category":"Fountain Pen","description":"It has taken a few years, but we've finally added it to our \"Standard Models\" collection of pens. \nThe original rainbow custom pen. From our friends at Diamondcast, we present a beautiful, multi-color swirled pen they have called the oil slick. We created this model back in early 2018 and debuted at the DC Pen show.  We named it Bifrost after the old Norse mythological \"Rainbow Bridge\" connecting the realms of the universe.\nThis is one of the first pens we offered our colored plated nibs on. This pen looks good with nearly every plating color we offer on our nibs. The optional plating can be selected upon checkout.\nThe body finial features a dragon-scale medallion and the cap finial features our logo medallion in rose gold. The cap posts securely by screwing onto the end of the body. ","images":["https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0046_abae5b3e-7160-4e03-be50-00441d68c3cb.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0054_99ad5ccf-622e-4d4b-9080-6d138e724e58.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0043_86a5ea4d-e8a2-4d29-b8d9-7c2c9f6f855e.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0044_a851d3e1-e1de-4de5-9e11-fa2848f9b0a5.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0045_42616a2a-4d33-4a54-81d5-889a427930c2.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0047_26ab9fe5-7536-466e-9a0b-1c77a959c158.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0048_9aeaecaf-cd02-4850-be2e-d4991c86b777.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0049_9edb33f1-4cb0-4c48-b35d-2c3246f94638.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0050_5594d15e-9592-471e-9ee6-feea004a19ad.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0051_428cfcd3-210a-4a1f-a12c-86d1fe0c5aa2.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0052_9c3d6aa2-a605-418e-98ae-87d821ae3c98.jpg?v=1601818091","https://cdn.shopify.com/s/files/1/0329/5117/3260/products/DSC_0053_dc6dde70-2afa-44f6-88c0-dfe799bb57e9.jpg?v=1601818091"],"price":224.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.108Z"},"share_url":"https://firestarter.network/l/lst_-PT5cjLV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
