Mando helmet options for kids

[Angelman]

I've seen the Jango and Boba Fett two part helmets with the kids Rubies kits.

Are there any other low cost options? (given how fast the kids grow, and how quickly they lose interest in a costume and want a different one).

I'm hopefully (fingers crossed) taking some time of work next week, I've got plastic bins and templates ready, but realised I don't have helmets sorted.

Thanks in advance for any ideas and suggestions
