This 3oz (per dozen) dauber (80ml) features an easy to hold oval "pen-grip" bottle with easy flow adapter! These daubers have a standard size tip that is easy to remove and replace. Daubers are more convenient than chips because you don't have to worry about chips sliding off the card, causing you to lose track of which spaces have been called. These markers are perfect for Bingo nights! See below for a wide variety of colors to choose from.
