I wouldn't trust them. they are a .onion and the products they have advertised are having stock images pulled from google. it seems rather dodgy to me.
would you mind to explain how .onion is less trustworthy than .com?
On a .onion you send network traffic though multiple computers, that information is also encrypted providing a large amount of anonymity, servers hosted on .onions are hidden services making them very hard to take down therefore they are a safe haven for scammers and such.
