Annual Ring is designed to reduce the use of paper.There's a buttom with the roll to prevent paper from dirty and ash,and the buttom has a pattern of annual ring,the more paper we use,the bigger annual ring appears.It will remind users of a crisis and fact that the lost years of the tree may be the years we will lose.
Just a little design can help us use paper roll clean and easy in everywhere.If we need to use it in the toilet,we just need to pierce the buttom.When we use it in work or study place,the buttom can help us contain pieces of paper we used momentarily when the seat is far from the dustbin to save time and make table clean.
