Concrete Countertop Mold Inside Corners

These are corner molds for forming inside corners on a concrete countertop mold. There are 2 different corner sizes in both 1.5-in and 2-in heights. The offset on each end is set to fit a melamine bullnose shelf. The corner plugs are made to plug the screw holes so concrete does not cover the screw head.
