If your fridge is always stocked up with a number of items and labelling the shelves won’t work for you, then here is a solution. You can opt for adjustable fridge trays/drawers and keep them on the shelves. Now you can label these trays and easily store different items on one shelf in an efficient manner. Similarly, you can also go for dividers which will keep food items away from one another by providing a horizontal barrier between them.
