{"type":"firestarter.listing","listing":{"id":"lst_6Zo1HCag","product_name":"Bigidesign x Chaves Pens","category":"Writing Instruments","description":"Some collaborations happen because they're planned. Others happen because they simply make sense.\nFrom the first conversation, it was obvious both brands shared the same philosophy—clean design, premium materials, and products built to be used every single day. The result is a collection that feels familiar to fans of both brands while bringing something entirely new to the table.\nThis limited edition collection includes two of our most popular writing instruments: the Fountain EDC and the Base Line Bolt Action. Both are precision machined from solid titanium and available in our signature Stonewashed finish and stealthy DLC Black.\nThe Fountain EDC features a premium German-made Bock 180 Extra Fine nib, an addicting pull-cap design, and compatibility with international ink converter for an exceptional writing experience.\nThe Base Line Bolt Action delivers the satisfying action our customers know and love, paired with seamless compatibility across hundreds of popular Parker style refills. Clean lines, dependable performance, and everyday reliability make it a pen you'll reach for every day.\nWhether you're a collector, a knife enthusiast, or simply appreciate thoughtfully designed tools, this collaboration brings together the best of both brands in a pair of writing instruments built to be carried, used, and enjoyed for years to come.\nWhat’s in the box (for each pen):\n\nChaves Titanium Fountain EDC Pen w/ Bock 180 Extra Fine nib (or) Chaves Base Line Bolt Action Pen\nKaweco Ink Converter (Fountain only)\nSchmidt P900 Refill (Base Line Bolt Action only)\nSpare O-rings\nLifetime Warranty\nFree Worldwide Shipping\n\n","images":["https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01478_8c4b42e1-0807-4016-ba31-65128d1551d9.jpg?v=1783959624","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01467.jpg?v=1783962520","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01494.jpg?v=1783959639","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01456_1d890a59-3164-4567-9b1c-867eabfb0230.jpg?v=1783960247","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01459.jpg?v=1783959663","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC01495.jpg?v=1783959692","https://cdn.shopify.com/s/files/1/1353/1287/files/DSC02357.jpg?v=1783959705"],"price":120,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-07-14T18:45:26.805Z"},"share_url":"https://firestarter.network/l/lst_6Zo1HCag","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
