The K3 Ultramulti is a beast of a keychain tool – it packs a crazy amount of features into a tiny 40-gram package.

Main light hits 800 lumens with a focused beam that reaches out there, perfect for walking at night or finding stuff in the dark.

But that's just the start – it also has a red laser pointer for alignment or presentations, and a 365nm UV light for checking IDs, spotting hidden stains, or inspecting for leaks.

Wait, there's more.

It's got a built-in ignition module too – press and hold for 2 seconds to get a flame, auto shuts off after 7 seconds.

Handy for lighting camp stoves, candles, or starting a fire in a pinch.

Also has side-mounted RGB lights with multiple modes – red/blue flash, red flash, blue flash, RGB pulse, and RGB chase.

Great for visibility or just looking cool.

Magnetic side mount lets you stick it to metal surfaces, and the hat-brim clip turns it into a lightweight headlamp.

Keychain-ready so you'll never forget it.

Battery is a 750mAh polymer lithium cell that charges via USB-C – about 90 minutes to full, giving you 2.5 hours on the main beam or 4.5 hours on side light.

IP65 weather-resistant, so rain won't kill it.

Compact, rugged, and loaded with features.

Perfect for outdoor enthusiasts, campers, mechanics, or just anyone who likes having a super versatile tool on their keys.
