Hi Phatcharee,
Regarding to following pics provided from you previously, we supposed those 3 returned new parts are referred to right hand sided pic, that are no damaged, rust or peeling paint as we checked in HK, but may be the length problem.
However, you do not send us those damaged, rusting parts to us (refer to below used parts for 1 year).
Maybe it’s better to send below used parts with damaged, rusting paint to us for further inspection.
