A tumbler used to have a pointed or a convex bottom that made setting it down very difficult. This made the glass “tumble” over when the user set it down. The point of the glass was to get the user to finish all of the contents before he or she put the glass down. The tumbler has now evolved to have a flat bottom, making it possible to set down without spilling the contents. Tumblers are now found in a majority of homes and can even feature lids. Find the right tumbler for you or your restaurant and get new styles, or an old style for kicks and giggle.
