According to what you said, give some suggestions. First of all, what Canon 0 10 1 sells on the market is guaranteed to be no problem; Secondly, do you mean the outer packing box seal or the sales packing seal? The seal of the sales package is sealed in the warehouse, because some camera categories need to put insurance cards or something, but there is no problem of tearing and pasting; Finally, you can check the authenticity of this machine online, or call Canon's hotline center and ask them to check the authenticity according to the information such as the fuselage number. Then decide whether to return it ~
