If you are transporting jewelry, die, or assorted small items, egg cartons are an excellent solution. Each small section creates a perfect encapsulation for whatever you need. With indentations, the small parts have limited risk of mixing with each other.
Cutting an egg carton apart can also support odd shaped items. If you have any products that don’t conform to a box shape like a vase or other trinket, you can support the item horizontally with egg carton. That way, the item will not roll, but will be safely contained.
