I can't all these grey marbles because the grey marbles I have are darker than these and I can't call them white marbles because they are too greyish so light grey marbles it is before I lose mine :).
It’s important to keep your Ants Off tray from touching surfaces like walls which will give ants access to it, so don't forget to purchase my anti slip bumpers with your Ants Off purchase if you think your diner might move the table while eating. Also helps keep it in place if knocked.
