My daughter loves Minions and she loves Star Wars. It is no surprise she insisted on having these figures.
At $33 shipped, this is the cheapest set I could find. It appears there are a bunch of knock-offs available on the interwebs. If you want a collectable set, I am fairly sure these are not they.
