I have a 72" tall and 36" wide metal storage cabinet in my playroom and the magnets go on there. I keep them at the top out of reach and they must ask for them. Mostly they are a set of farm animals and dinosaurs I got at a garage sale - think they are a melissa and doug product actually. I have the letters and other smaller items in a bin on the cupboard that come out when the older ones ask and are then put away when done so the little ones dont't have continuous access.
