A graph G is anti-magic if there is a labelling of its edges with 1,2,...,|E| such that the sum of the labels assigned to edges incident to distinct vertices are different. In this paper, we prove that if G is k-regular for k=2, then for any graph H with |E(H)|=|V(H)|-1=1, the Cartesian product H@?G is anti-magic. We also show that if |E(H)|=|V(H)|-1 and each connected component of H has a vertex of odd degree, or H has at least 2|V(H)|-2 edges, then the prism of H is anti-magic.
