I believe they are an inch and a half but they could be 1 in, not actually right now, and it's the full socket set, couple of breaker bars, and large toothed ratchet. It's brand new never been used, just doesn't have a case. Might even let that little grenade box go with it. Idk. When I opened my shop I thought maybe I'll need them Sunday... Here we are years later and I still haven't been able to work on a tank... Dang! 500 obo.
