{"type":"firestarter.listing","listing":{"id":"lst_LZHuJg4F","product_name":"Switch Pen","category":"Switch Pen","description":"You asked for it...\nAfter releasing the popular Slim Switch in 2024 we're excited to offer a standard diameter version with deep-carry clip in multiple finishes and lengths for more ink refill compatibility. Based on the Magnus ClickShift™ V1, our version is rebuilt from the ground up to simplify production, tighten up the action, and improve the overall feel. The three-piece mechanism is machined grade 5 titanium and a stainless steel or C63000 bronze actuator switch to provide a smooth action while maintaining durability.\nNote: One difference from our previous version apart from the thicker diameter and bent clip is the position of the \"switch\" is higher up on the pen, making the overall length shorter and comparable to our Bolt Action pens.","images":["https://cdn.shopify.com/s/files/1/0082/2840/5353/files/10-ST1-TTM-STW.jpg?v=1752683403","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/10-ST2-TTM-STW.jpg?v=1752683411","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/10-ST1-TTM-TTM.jpg?v=1752683377","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/10-ST2-TTM-TTM.jpg?v=1752683393","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery02_625c730e-6e2a-4956-a45c-ca29cffe31e0.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery08.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery03_89cb7458-64d9-4ebb-b7d9-020073ecdff5.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery05_9fc72bce-2c67-4b52-b64b-72e5779567fc.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery06_3204bca4-2501-46b3-ae28-58d63df98cc6.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_mechanisms.jpg?v=1752685734","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery10.jpg?v=1752685862","https://cdn.shopify.com/s/files/1/0082/2840/5353/files/switch_gallery11.jpg?v=1752686103"],"price":129,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:17.981Z"},"share_url":"https://firestarter.network/l/lst_LZHuJg4F","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
