3 “horn” vases / glasses

3 small vases made from horn. At least two of these were promotional with logos painted on. One still has remnants of it. One has a faint outline where the logo used to be. None of these are liquid proof. They have wooden corks at the bottom that would not hold liquid. Would be great for pen holders or a vase for some small dried flowers…? Tallest one Meaaures 7” tall; shortest one measures 5” tall.
