Zero-G Snapgate Mini Carabiners
2 ¾ inches (7cm) long, made to a high standard in the EU from hardened alloy, with anodized finish and laser-etched branding

The best small carabiners I can find. The gates are well put together with good springs and chunky rivets, and they don't wobble out of alignment like the cheap ones from the far east. Nicely finished. (You do not want anything with sharp points or edges anywhere near a taut kite line.)

Weight: about half an ounce - 15.2 grams
Assorted colors
