Amazon doesn’t list separate dimensions for each of the three sizes, can I get a comparison?

SIZE BREAKDOWN: ONO Original: 3.40" x 0.85" x 1.75" ONO Junior: 3.00" x 0.75" x 1.50" ONO Mini: 2.20" x 0.85" x 1.75"

Do you plan on making one with a smaller diameter?

ONO now has a smaller version available.

My hands sweat alot, will this rust?

No, The barrels are made of aluminum which doesn't oxidize or rust. I'm not sure about the barrings inside but they shouldn't be affected unless you sweat to the point where you are coating the objects you hold in moisture.

Are these allowed in carry-on baggage?

Yes, these are allowed in carry-on baggage! I have heard customers being stopped due to its unique shape, but a simple explanation/demonstration will clear it right up!
