This set of 12 rubber duckys are just adorable. You'll receive a combination of the four designs shown for a total of 12 ducks. Each ducky measures approx. 5.1cm x 5.1cm . They do not squeak but do have a hole in their beak for squirting water. They do not float upright. These make great little party favours or gifts for doctor's offices to pass out to young patients.
