pure and simple

pure and simple idiom
No more and no less, plainly so, as in This so-called educational video is really a game, pure and simple. This expression is very nearly redundant, since pure and simple here mean “plain” and “unadorned.” Oscar Wilde played on it in The Importance of Being Earnest (1895): “The truth is rarely pure and never simple.” [Second half of 1800s]
