Is the Dukap Inception carry-on size?

No. At about 21.65 inches wide it is a check-in case, not a carry-on. Measure against your airline's checked-bag limits before you fly.

What is the shell made of?

It is a blend of ABS and polycarbonate. That keeps it light and impact-resistant for the money, but it flexes more than a full polycarbonate shell.

Yes, a built-in TSA lock is part of the case, so security can open it without breaking anything. You set your own combination.

Four double wheels, so it rolls upright and spins. The doubles track well on smooth floors but can catch on gravel or deep carpet.

No. There is no expansion zipper, so the packing depth is fixed. Packing cubes help make the most of the space.

Yes, the telescopic handle locks at multiple heights, and there is an ergonomic top grip for lifting.
