{"type":"firestarter.listing","listing":{"id":"lst_sT5HQ_NS","product_name":"GMK CYL Hyperfuse Origins Keycap Set","category":"Keycaps","description":"Doubleshot ABS Set\nThe GMK CYL Hyperfuse Origins Keycap Set revives one of the recognizable custom keycap colorways from the 2010s keyboard scene. Inspired by Nike’s Hyperfuse footwear technology, the set combines dark gray tones with cyan and purple accents. This modern release preserves the character of the original design while updating it with GMK’s CYL sculpting and doubleshot ABS manufacturing.\nGMK CYL sculpted profile\nThe CYL profile uses a cylindrical top surface with sculpted row heights for a familiar typing angle across the board. Keys are arranged in the standard 1-1-2-3-4-4 row configuration used in modern GMK sets, offering compatibility with a huge range of keyboard layouts.\nDoubleshot ABS construction\nEach keycap is produced using doubleshot injection molding with ABS plastic. Legends are molded as a separate piece of plastic rather than printed, allowing them to maintain clarity and legibility over time. The smooth ABS surface also gives the set the signature texture and sound profile associated with classic GMK releases.\nFlexible kit configuration\nThe Hyperfuse Origins is divided into three kits: Base Kit, Numpad Kit, and Unusual Kit. This structure allows users to purchase only the coverage they need for their keyboard layout. The Numpad and Unusual kits also include lock indicator keys with south-facing LED windows for scroll lock, caps lock, and num lock functionality.\nProduct highlights\n\nGMK CYL sculpted profile\n\nDouble-shot ABS construction\n\nClassic Hyperfuse gray, cyan, and purple colorway\n\n1-1-2-3-4-4 row sculpting\n\nThree-kit layout system for flexible compatibility\n\nSouth-facing LED indicator windows on select keys in the Numpad and Unusual kits\n\nSpecs\n\nManufacturer: GMK\n\nProfile: CYL\n\nMaterial: ABS plastic\n\nLegend manufacturing: Double-shot injection molding\n\nRow configuration: 1-1-2-3-4-4\n\nAvailable kits: Base Kit, Numpad Kit, Unusual Kit\n\nIndicator key support: South-facing LED windows on select keys\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691552.png?v=1780080489","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691554.png?v=1780080429","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691557.png?v=1780080368","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691555.png?v=1780080308","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691560.jpg?v=1780080249","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691559.jpg?v=1780080188","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691562.jpg?v=1780080130","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-gmk-keycaps-gmk-cyl-hyperfuse-origins-keycap-set-1240691561.jpg?v=1780080070","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/Hyperfuse_Base_Kit_labeled.jpg?v=1783380591","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/Hyperfuse_Numpad_Kit_labeled.jpg?v=1783380591","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/Hyperfuse_Unusual_Kit_labeled.jpg?v=1783380591","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/Hyperfuse_Accent_Kit_labeled.jpg?v=1783380591"],"price":150,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:55.764Z"},"share_url":"https://firestarter.network/l/lst_sT5HQ_NS","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
