Use both sides! / sticky note

We usually just use the top side of the sticky note,ignore using its rear,cause the waste of paper.To solve this problem,I design this Double-sided Sticky Note,it advocates people use both sides of post-it note.When we use up the top side of the note,we can tear the note apart along the tracks,turn to the back side of it,so as to reuse the note.One small change,make a step forward to the green environmental protection.
