K.Narong mentioned that this kind of wooden pallet was sent to both of domestic & export for long time without any complaint. He just got the complaint about this problem and he already fed back to supplier together with picture suddenly. K.Narong mentioned that normally we have random check before reception, once he found defective pallet it will be returned to supplier. However, random check can't cover 100% so, if some pallet has defect, it is possible to send to customer.
