Is this suitcase durable enough for checked baggage?

The front is polycarbonate and the back is ABS, a common hard-shell mix that handles knocks and scratches. ABS is the softer, more brittle of the two, so the back is the part most likely to scuff or crack under rough handling.

What sizes does it come in?

It is offered as a cabin size, a medium and a large. Only the large has the top expander that adds storage space.

Does it have a lock and spinner wheels?

Yes. It has a built-in lock and four double wheels that swivel 360 degrees, plus an adjustable telescopic handle.

How do I clean the printed shell?

Empty the case first, pretreat visible stains, then wipe with a soft cloth or soft brush using warm water and mild detergent. Let it air dry.

Is the print likely to scratch off?

The design is printed on a canvas surface encapsulated in the polycarbonate shell, so the graphic sits under the clear layer rather than on top of it.
