If you are afraid of melting, you can add a layer of foam to the outside of the gift packagingCardboard Tubes Packaging company to insulate it. The main reason for express delivery is that the environment is too hot during transportation, so there is no reason for chocolate to be broken.

I suggest you add another letter to explain the reason and convey your thoughts by the way. Ha ha. The packing order is from outside to inside: express box, foam insulation, gift packaging, gift box, chocolate. Last good luck
