It is mind boggling.
It means either
1) the brand don’t produce many of the same item
2) there are many people with disposable income in this world who are easily influenced by celebrities
Even if we did the calculation 1 item per country only for the backpack it is a total of 95k$ usd which is a lot of money, and while this is all impressive, the kombucha situation imo is even more surprising, it's not easy to increase sales by up to 500% and they even recently won brand of the year, so I'm really glad he's using his influence to help such businesses.
