Package waste and contamination of the bottom of bath tissue are the two problems In use. We have observed the inconveniences and our reflections on improvement have resulted in this new design product. Our package of bath tissue consists of an upper cover and a lower cover, with the radius of the latter slightly bigger than the former. Stack the two covers and make them a base for your bath tissue. We can thereby make full use of the package，prevent waste and adress the concerns of sanitation.
