I received a small package in the mail with what looks like a L shaped adapter but it says “10gb” on it. How can I safely look to see if there’s anything on it?

received a small package in the mail that has a usb-c to usb-c L shape looking adapter. It has a return label to Kyrgyzstan. It doesn’t really say anything else except it was declared as sale of goods to customs.

My computer is the only thing I have with a usb-c port but I don’t want to just plug it in without safety precautions, especially since I never ordered a usb-c anything ever.
