Abstract: Suppose $ X$ is an infinite-dimensional operator space and $ n$ is a positive integer. We prove that for every $ C > 0$ there exists an operator space $ \tilde{X}$ such that the formal identity map $ id : X \to \tilde{X}$ is a complete isomorphism, $ I_{\mathbf{M}_n} \otimes id$ is an isometry, and $ d_{cb}(X, \tilde{X}) > C$. This provides a non-commutative counterpart to a recent result of W. Johnson and E. Odell.
