The contents are empty cans. To prevent any issues during shipping, they will be washed with dish soap, dried, and then shipped. The area around the opening will also be cleaned as much as possible, and each can will be individually waterproofed and wrapped in bubble wrap before shipping. If you're interested, please consider purchasing. *These are all empty cans that were consumed within the last year. If you comment with the number you need, I will try to adjust the price as much as possible, but I can't guarantee I'll be able to meet your expectations. #DIY #Collection #CoffeeCans #CraftingMaterials
