{"type":"firestarter.listing","listing":{"id":"lst_FJU7PriI","product_name":"Titanium Pen Mechanisms","category":"Pen Mechanism","description":"\nDue to overwhelming demand, we are excited to offer our latest TiButton® and NottaBolt® mechanism for individual purchase!\nEvery component of our mechanisms, from the button to the screw, is crafted from Grade 5 Titanium, with the exception of the custom-made stainless spring. This listing includes our TiButton® Right Hand Double Lock and Single Lock, and the NottaBolt® Right Hand variations, as well as the TiButton® Left Hand Double Lock and Single Lock and the NottaBolt® Left Hand variations.\nOur pens are meticulously designed to be fully modular, allowing you to customize each component to your preference. Since the TiButton® release in 2019, we've included an indicator on every pen we've machined—a small \"cut\" where the pen body and mechanism connect. If you have an older pen, we cannot guarantee that the new mechanism will align perfectly with the pocket clip. However, you can send your pen to us, and we will make the necessary adjustments to ensure it fits properly!\n\nYou can email us at: info@nottinghamtactical.com prior to purchasing should you have any questions! ","images":["https://cdn.shopify.com/s/files/1/0051/4614/8898/products/TiButtonGroupPicture.jpg?v=1680016080","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/NottaBoltGroupPic2.jpg?v=1722355107","https://cdn.shopify.com/s/files/1/0051/4614/8898/products/TiButtonRIghtHandDoubleLock.jpg?v=1722355113","https://cdn.shopify.com/s/files/1/0051/4614/8898/products/TiButtonRightHandSingleLock.jpg?v=1722355113","https://cdn.shopify.com/s/files/1/0051/4614/8898/products/TiButtonLeftHandDoubleLock.jpg?v=1722355113","https://cdn.shopify.com/s/files/1/0051/4614/8898/products/TiButtonLeftHandSingleLock.jpg?v=1722355113","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/NottaBolt_Low_Baller_Right_Hand.jpg?v=1722355057","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/Nottabolt_High_Baller_Right_Hand.jpg?v=1722355063","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/NottaBolt_Low_Baller_Left_Hand.jpg?v=1722355069","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/Nottabolt_High_Baller_Left_Hand.jpg?v=1722355081","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/TiButton_RHDL_Black_Cerakote.jpg?v=1754514451","https://cdn.shopify.com/s/files/1/0051/4614/8898/files/TiButton_RHSL_Black_Cerakote.jpg?v=1754514462"],"price":75,"currency":"USD","in_stock":true,"inventory_qty":119988,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:47.770Z"},"share_url":"https://firestarter.network/l/lst_FJU7PriI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
