V-GAP / Packaging

People deal with a wide variety of packaging every day, but it is not convinient to open it,especially when holding liquid or powdered goods.If the opening is too large,it would be hard to pour it out,and this is really confused.
V-GAP bring a new solution of the problem.Combining the declining gap and the vertical gap,you are allowed to to tear out a relatively fixed shape of the opening.
