The Gibson Ultra Patio 12 piece set is simple and classic, featuring embossed banded edges. This set is constructed with tempered opal glass that is stronger than regular stoneware. Internal tests show Ultra-Dura out performs other stoneware dishes by as much as 3 times in terms of impact resistance and 4 times in chip resistance. The high fired glaze creates a more hygienic, fully vitrifies surface with almost zero porosity. This set is dishwasher, microwave, and freezer safe for easy storage, clean up, and reheat. Comes with service for four.
