Each hand-etched design is 100% permanent, and completely dishwasher safe. I use a sandblasting technique that removes a small amount of surface glass, giving the design a frosted look. No designs are painted on or temporary, and I personally guarantee the permanence of each design. Sandblasting also has a smooth, even finish, unlike laser-etching and acid cream etching which can be both messy and uneven.
I do not manufacture any of the glassware myself, so availability of styles and/or quantities for custom orders may be limited. However, I am happy to work with you to make sure you are getting the style and quality of glassware you are looking for. All glassware I use is made in the United States.
