These festive drinking glasses are hand-painted. Each glass has a different color palette. First I swirl the different color paints to create the flowing pattern you see. Once that is complete & it has dried I create the wave pattern on the edge of the color & add the white painted accent dots by hand. Once that all dries for three days I bake them in the oven to cure the paint. They are top rack dishwasher safe! Do not let them soak in water for an extended period of time. The surface area of the paint is smooth. This listing is for four glasses, the pitcher is available on a separate listing. Set Of Four Festive Hand Painted Glasses-14 Oz - 5.25
