Ok, if you do have anvils to store, that’s fine and we welcome them. But when it comes to loading up your packing boxes, keep it light. Packed boxes should never weigh more than you can comfortably lift. It’s also a good idea to avoid overstuffing a box, causing it to bulge from the top or sides. Making sure your packing boxes stay square, is the best way to keep everything stable – and avoid unfortunate topples – when you stack all those boxes in your storage unit.
