Mega Vases1.5" x 24" Eiffel Tower Glass Vase - Set of 12, Clear

I ordered 24 of these vases. I tried to place colored marbles inside the vase so as to spice up the appearance. I quickly discovered that the vase neck diameters came in three different sizes. The two smallest sizes were too small to insert marble/ small colored marble stones. Several times a small marble would get stuck halfway down the neck of the vase, preventing the vase from filling up. Once we tried to retrieve the marble, the vase itself shattered with the slightest pressure. Quality of the glass is poor. Other than that the vase looks very nice. .
