{"type":"firestarter.listing","listing":{"id":"lst_nahrT7Px","product_name":"B36 - (Diamondcast) - Evancio - Heimdhall","category":"Fountain Pen","description":"When we created the Bifrost, we wanted a pen to pair with it. Running on the norse theme (mythology being a hobby of mine), I set out in collaboration with our friends at Diamondcast to create a pen big enough and bold enough to pair with our \"rainbow bridge\" pen. Taking hints from mythology and current popular culture, we created this silver, bronze, and black beauty.\nThis is a rather large pen. The cap is approximately 18mm in diameter, the body 16mm at its widest point, and the section about 15mm at its widest. This pen works very well with a bock #8 titanium nib, but can also be paired with a standard steel #6.\nFrom the Encyclopedia Britannica:\nHeimdall, Old Norse Heimdallr, in Norse mythology, the watchman of the gods. Called the shining god and whitest skinned of the gods, Heimdall dwelt at the entry to Asgard, where he guarded Bifrost, the rainbow bridge. He required less sleep than a bird, could see 100 leagues, and could hear grass growing in the meadows and wool growing on sheep. Heimdall kept the “ringing” horn, Gjallarhorn, which could be heard throughout heaven, earth, and the lower world; it was believed that he would sound the horn to summon the gods when their enemies, the giants, drew near at the Ragnarök, the end of the world of gods and men. When that time came, Heimdall and his enemy Loki would slay each other.","images":["https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163325.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163219.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163244.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163311.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163223.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/JUN0926_PHOTO-163230.jpg?v=1781090594","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/Hinze-Custom-Order-Form-1_Page_1_a1ec2a5d-1be0-4bed-8f6e-0966e4b94f79.jpg?v=1770071443","https://cdn.shopify.com/s/files/1/0329/5117/3260/files/Hinze-Custom-Order-Form-1_Page_2_31ea60f9-53e8-4b7b-a660-8bcdb5a83c72.jpg?v=1770071443"],"price":274.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:20.849Z"},"share_url":"https://firestarter.network/l/lst_nahrT7Px","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
