Why not give anniversary party favors that are really useful, like these custom clear glass mugs. Used both hot and cold beverages, each favor measures 3 1/2" tall x 4" in diameter, with a 10 ounce capacity. Note the classic coffee mug shape with a sturdy glass handle. An added bonus is that they have a screen print design that stays on the glass versus a decal that peels off.
You can purchase a box for an additional .70 each. It comes with clear window display front and separate white satin bow with sticky back for easy application. Box Dimensions: 4" tall, 4.75" wide, 3.25" deep. Boxes are shipped flat - some assembly required.
