The dissolvable material should be strong enough to support the non-dissolvable metallic material which serves as teeth to set into the casing during the function of the downhole tool. The dissolvable material can include but is not limited to a polymeric material or a metallic material. At least a part of the slip is able to be set as well as be dissolved.
