As deep understanding of excellent product as our mission is your perfect operation experience and feeling, thus Kinghope sanitary staff take extremely strict attitude towards each product; we shall refuse any radioactive raw material even at beginning with material selection, and pack and return ceramic or glass semi-finished product if they are little defective; also firmly unassembled and reinstall that even only has 0.1cm abrasion; and no any rusted screw exists in Maike product even in some place that we can not see; moreover, for the sake of more smooth product while touching it, whose corner must be manually grinded by special technician, since exquisite product comes from repeated burnish.
