Please folks, what is the net weight of this product not including shipping packaging??

The chocolate is packaged in a thin box

Will the chocolate melt if shipping oversea?

You have a better chance if it not melting as the months get cooler. I have kept these in my car in the summer (live in CA where it is 90-100) average summer day and the balls were still in tact. It helps that they are individually wrapped so that contains them and they aren't going to melt together into a clump. you can put them in the refrigerator when they arrive and should be fine but they may not be perfect.

How many carbs in one

15 total carbs in 3, so 5 per one

How do you ensure the chocolate won't melt in transit? Can it be shipped with dry ice?

I've ordered many of these delicious, delicious chocolate truffles and I've never had a melting problem. They've never shipped them in cold packs either. But how to ensure that the chocolate won't melt? Cross your fingers and hope all will go well. :)
