This Rolling Tray has been designed to ensure that you have everything you need in the palm of your hand. The size is perfect to fit on the table or in your lap. There is a spot for your Grinder or The DNA glass Jars. It comes standard with our paper dispenser. There is a spot to keep your leftover rubbish and a generous area to do your rolling. The inside walls are all sloping in case you are a scooper and we also have an open corner edge in case you are a sweeper.
