It should be quite safe. The buyer pays the money to PayPal first, not to the buyer. eBay acts as a middleman. With eBay's strength and reputation, both buyers and sellers should have full trust.

Let’s take a look at how PayPal’s operations protect sellers:

1. The buyer receives the goods and confirms with eBay: eBay will transfer the temporarily collected money after receiving the confirmation. Pay the payment to the seller;

2. The buyer receives the goods without confirming it to eBay: within a certain period of time, such as within a month, eBay assumes that the buyer has received the goods and automatically pays the temporarily collected money. To the seller;

3. The buyer receives the goods and lies to eBay that he has not received the goods: the seller presents the shipping documents to eBay, and eBay arbitrates. eBay confirms that the seller has shipped the goods and the buyer has received the goods, and will pay the temporarily collected money to the seller;

4. The buyer receives the goods but requires a return: Negotiate between both parties. While the negotiation is pending, the temporary collection will be temporarily frozen.

Judging from the above four situations, through PayPal, it is impossible to have a situation that is unfair and disadvantageous to the seller, such as losing both money and goods.
