Using these board game box bands is super easy. Just wrap them around your board game boxes. The large ones are for bigger boxes, and the medium ones for smaller ones. When traveling, make sure the bands are firmly in place to keep the lids from opening. As for maintenance, there's not much to worry about. Just keep them in a dry place when not in use. If they get dirty, you can gently wipe them with a damp cloth. Don't expose them to extreme heat or sharp objects, as this could damage the elastic fabric.
