I bought an item in eBay and the sender shipped it about 1 week ago from US. Out of a sudden few days before, when the package touched down in Malaysia, the sender informed me that he accidentally shipped the wrong product and requested me to refuse/reject the package so that it will be returned.

Just wanna ask here whether had anyone went through this process before? To reject/refuse the package. And how long it took for it to be shipped back.

My item is shipped via USPS.

You had to call the courier company.Well you can just accept the parcel and see whats inside.

lol, I wish I could but the sender had requested that the package should not be opened. It's very tempting to open it up though.

The courier company?
Pos laju or pos malaysia will be the one sending the item to you.

If you accept it, and then ship it back, wouldn't you have to pay for postage in the other direction?
