yes, you can. As long as the case does not have a plastic see through cover on it. The plastic see through covers will adhere themselves to the glass screen protector if exposed to heat. Leather or other material cases are just fine. Some cases will discolor the protectors because the material is porous and will absorb the dye in the leather of material cases. We recommend a silicone type case that is not really tight fitting to go with the glass screen protector.
