The tritium vial sits inside a precision quartz tube with 92% light transmission, surrounded by a CNC-machined Gr5 titanium body that weighs just 10.7 grams. The construction is fully serviceable. Two silicone O-rings hold the vial in place, and when brightness fades after two decades, you push the old tube out and slide a new one in. The design includes a ceramic-tipped glass breaker at one end, a keychain hole at the other, and a floating core that\u2019s visible from all sides. Xedge ships it in six colors (Ice Blue, Apple Green, Red, Sunset Orange, Violet, Ocean Blue) and two finishes (sandblasted titanium or black coating). Pricing starts at $25 for a luminescent vial version and $45 for tritium.<\/p>\n<p>Designer: Xedge<\/p>\n<p><a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.kickstarter.com\/projects\/459774293\/noxti-a-titanium-glow-tube-light-for-everyday-carry?ref=a3av9g\" target=\"_blank\" rel=\"noopener\"><strong>Click Here to Buy Now: $30<\/strong><\/a> <del>$42<\/del> (28% off).

At 10.7 grams, the weight registers as barely-there on a keychain, roughly equivalent to two US pennies. The Gr5 titanium alloy (also known as Ti-6Al-4V) is the workhorse material of the aerospace industry, chosen for its exceptional strength-to-weight ratio and total resistance to corrosion. This alloy doesn\u2019t rust, doesn\u2019t tarnish, and doesn\u2019t degrade in salt water, sweat, or extreme temperatures. Xedge tested the assembly from -20\u00b0C to 50\u00b0C, and the glow remained steady throughout. The body is CNC-machined, not stamped or cast, which means tighter tolerances and cleaner geometry.<\/p>\n<p><a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.kickstarter.com\/projects\/459774293\/noxti-a-titanium-glow-tube-light-for-everyday-carry?ref=a3av9g\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.kickstarter.com\/assets\/053\/003\/094\/36b1824570c11e7197420ac4c5d0a79f_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773832536&amp;width=680&amp;sig=Mm8GTiASxSW06UWQ1KhrxQoTmmdPNtIFsJgEgJmDWd8%3D\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/04\/09\/this-45mm-titanium-keychain-glows-for-25-years-without-batteries-using-pure-material-physics\/\" data-jpibfi-post-title=\"This 45mm Titanium Keychain Glows for 25 Years Without Batteries Using Pure Material Physics\" data-jpibfi-src=\"https:\/\/i.kickstarter.com\/assets\/053\/003\/094\/36b1824570c11e7197420ac4c5d0a79f_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773832536&amp;width=680&amp;sig=Mm8GTiASxSW06UWQ1KhrxQoTmmdPNtIFsJgEgJmDWd8%3D\"><img loading=\"lazy\" class=\"lazyload\" decoding=\"async\" src=\"https:\/\/i.kickstarter.com\/assets\/053\/003\/094\/36b1824570c11e7197420ac4c5d0a79f_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773832536&amp;width=680&amp;sig=Mm8GTiASxSW06UWQ1KhrxQoTmmdPNtIFsJgEgJmDWd8%3D\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/04\/09\/this-45mm-titanium-keychain-glows-for-25-years-without-batteries-using-pure-material-physics\/\" data-jpibfi-post-title=\"This 45mm Titanium Keychain Glows for 25 Years Without Batteries Using Pure Material Physics\" data-jpibfi-src=\"https:\/\/i.kickstarter.com\/assets\/053\/003\/094\/36b1824570c11e7197420ac4c5d0a79f_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773832536&amp;width=680&amp;sig=Mm8GTiASxSW06UWQ1KhrxQoTmmdPNtIFsJgEgJmDWd8%3D\"><\/a><\/p>\n<p>Quartz glass transmits 92% of visible light, far outperforming acrylic or polycarbonate alternatives that yellow and scratch over time. The tube encasing the tritium vial is hermetically sealed, protecting the vial from moisture, dust, and impact. Beta particles from tritium decay are so weak they cannot penetrate paper, let alone quartz. The radiation stays contained. If the tube somehow shattered, tritium is a gas that dissipates instantly with no lingering hazard. The engineering priority here is longevity. The quartz will still be optically clear in 2050.<\/p>\n<p><a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/www.kickstarter.com\/projects\/459774293\/noxti-a-titanium-glow-tube-light-for-everyday-carry?ref=a3av9g\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i.kickstarter.com\/assets\/053\/017\/088\/9e42d0e5153e74fc2bc592689fad5e4c_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773921419&amp;width=680&amp;sig=EEB2nbCQSqNu4ll6A7S9mxhhoZTs2LcRRDDP58E%2BgEM%3D\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/04\/09\/this-45mm-titanium-keychain-glows-for-25-years-without-batteries-using-pure-material-physics\/\" data-jpibfi-post-title=\"This 45mm Titanium Keychain Glows for 25 Years Without Batteries Using Pure Material Physics\" data-jpibfi-src=\"https:\/\/i.kickstarter.com\/assets\/053\/017\/088\/9e42d0e5153e74fc2bc592689fad5e4c_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773921419&amp;width=680&amp;sig=EEB2nbCQSqNu4ll6A7S9mxhhoZTs2LcRRDDP58E%2BgEM%3D\"><img loading=\"lazy\" class=\"lazyload\" decoding=\"async\" src=\"https:\/\/i.kickstarter.com\/assets\/053\/017\/088\/9e42d0e5153e74fc2bc592689fad5e4c_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773921419&amp;width=680&amp;sig=EEB2nbCQSqNu4ll6A7S9mxhhoZTs2LcRRDDP58E%2BgEM%3D\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/04\/09\/this-45mm-titanium-keychain-glows-for-25-years-without-batteries-using-pure-material-physics\/\" data-jpibfi-post-title=\"This 45mm Titanium Keychain Glows for 25 Years Without Batteries Using Pure Material Physics\" data-jpibfi-src=\"https:\/\/i.kickstarter.com\/assets\/053\/017\/088\/9e42d0e5153e74fc2bc592689fad5e4c_original.gif?fit=scale-down&amp;origin=ugc&amp;q=92&amp;v=1773921419&amp;width=680&amp;sig=EEB2nbCQSqNu4ll6A7S9mxhhoZTs2LcRRDDP58E%2BgEM%3D\"><\/a><\/p>\n<p>Two precision silicone O-rings grip the quartz tube at either end, holding it perfectly centered inside the hollow titanium body.
