Slightly smaller than a AA battery, the Darter is a micro-pen beautifully machined from aluminum and brass that writes with Cross Matrix Ballpoint refills. There’s also a secret inside. It’s got a built-in sewing kit. It includes 2 bobbins with 100mm of thread on each, & 4 No.10 Gold Eye Sharps needles. It’s the perfect size for your survival kit, dopp kit, or with its keychain-size form, your EDC. A funded Kickstarter.
