[Harry Potter] What items from the Wizarding World could be resold into the Muggle world for profit by an enterprising Muggleborn without arousing suspicion?

Let's assume a *barely* capable wizard who still has solid connections to their Muggle life decides to take advantage of their access to the magical world to earn enough to live a life of comfort and luxury there?

**Bonus Question:** Is there anything from the Muggle World they might be able to market to Wizards in a similar fashion?
