Square end that fits onto a ratchet/screwdriver. It rattled unlike a normal socket, didn't fit very well but the ratchet ball held it. Little problem. I then tried to insert a hex into the other end. I had to bend over and press him against a hard object with considerable force. Based on the picture I thought the black ring was magnetic but no, in one of the 6 corners there is a small ball that holds and seems to hold the hex. I tried oiling the ball and rocking it. Nothing. So I went back: when it comes to mundane things, I don't believe in too cheap to return. Revane said: Non-refundable. Inexplicable, unforgivable. They eventually gave in, but it was a long detour of over $6.
