  We show that, on the contrary to the usual claims, fully supersymmetric CP
violations in the kaon system are possible through the gluino mediated flavor
changing interactions. Both $\epsilon_K$ and ${\rm Re} (\epsilon' /
\epsilon_K)$ can be accommodated for relatively large $\tan\beta$ without any
fine tunings or contradictions to the FCNC and EDM constraints.
