I had orderd door hangers with a adhesive strip much like tape on the back side and I thought I had heard everything until 2 or 3 people called me up and said " your door hangers left sticky **** on my door , ill be sure not to use your service " I mean really ?! So I tryed to see what they where talking about I put it on my front door and really pressed on it and left it for an hour or so and it came right off. Idk the way I figure it if those people where that anal about calling me to not use my service im better off with out em !!!!!!!!
