... I would have used earlier

I use this tray in the garden shed. There I wear - depending on - ice bowls, glasses, etc. in the garden. Here I go through the door insect screens. That's with glasses every time a balancing act and are twice my glasses or ice cream containers already fallen down :-( With my new tablet glass does not slip so easily. The material itself and the knobs in particular provide stability. The tray can be cleaned in the dishwasher become.
