Abstract: A dabber for marking items such as bingo cards has a hollow head portion and a hollow handle portion providing the overall appearance of a hammer. The head portion has a check-valve operated applicator at each end, the applicators preferably being of different diameters. The head and handle portions are filled with a colored, indelible, transparent non-toxic ink. During use the player applies the desired applicator to the desired location by using a smooth, soft hammer-like motion while gripping the handle portion of the dabber. The dabber is cleaner and easier to use than prior art dabbers.
