"Sticky Tack is an easy and non-permanent way to decorate your walls. I am a college student and recently moved into my dorm and needed something that I could use to hang up some posters and cloth wall hangings. My friends recommended sticky tack and it has worked great so far it has kept everything up for the last month and it seems like it will stay for a while longer. It was pretty easy to use because all you have to do is take some out of the package and knead it for about thirty seconds and then just stick either a poster or a light wall hanging on the wall and then if you decide to take it down you can just pull it off. However one downfall of the product is that when you take it off it leaves a little residue but with some scratching you can get most of it off so it does not actually leave you with any permanent damage. Overall I would say that the product does exactly what it is advertised to do."
