A mobius strip made out of paper has 2 sides, the usual one and the edge.

You can make it out of some other material that you can smooth, i.e. so that it doesn’t have edges.

Come to think of it, doesn't a sphere have only one side?

How about things like Klein bottles that have no edges? (Although I guess that unlike a Mobius strip it's not possible to make a real one here on Earth so the quote from OP still holds)
