The holidays are over and you have a lot of tins left to store. Why not put them to good use? They are great for organizing. Since they are waterproof consider using them for your emergency kit supplies, or other sensitive items that need a sturdy container.
You could even use such ones as Altoids tins for items like sewing needles, paper clips and more! They might even make great drawer organizers in the bathroom or laundry area.
