customers can just send them back for no reason at all
But you don't have to accept unconditional returns unless your own policy and/or relevant legislation says you do. And you might choose to make the customer pay shipping for non-defective returns-- again if permitted by law.
Personally I'd save the worrying for customers who open a package, break the product, and then claim it was damaged in transit.
