no residue by xiaolong Lou from china
designer's own words:
drinks with paper cup are popular with us, but you may find that much drink residue is left in the corner dispersedly,so they have to be wasted. this design brings a good solution of making the bottom dented,so the residue will converge on the bottom,now you can absorb these residue absolutely without wasting them.
