Our glassware are hand-designed, hand-etched, hand-washed, & hand-packed. We are a small business in Greensburg, PA & pride ourselves in ensuring our quality is superb. Our glass products are sandblast-etched, NOT screen printed or laser-etched. This type of etching means that the designs will NEVER wash off or fade! You can literally feel the depth of the design in the glass. This mug holds 15 ounces. If you have any questions, let me know! Otherwise, happy ordering!!
