I apologize to you that I did not explain well. The item has not been damaged. The item listed at the box and contents in it were wrong. The items were two. The item number listed at the box was AAA, and parts in the box was BBB.
I'm sorry for not being able to explain you better. The item is not damaged. The serial number on the box was different from the item inside. it's 2. The serial number on the box is AAA and the inside is BBB.
