We can pretty comfortably state that you have never seen anything like this before. An electrostatic roller that attaches paper to walls and windows. What does this mean? No more tape, glue or thumbtacks and no residual traces left on the wall….really! You can hang any and all of your children’s artwork along with pictures, magazine clippings, the list just goes on and on. Just push the charge button on the roller to create the static charge and then roll it over the paper on a flat, interior wall, step back and viola! The kits come in themes and include the roller and a variety of colored sheets of polyethylene with images like unicorns, fairies, dinosaurs, etc. These hang really well on windows. If you have a budding, prolific artist you will love this roller. If you have a tween daughter who tapes and tacks up pictures of Justin Bieber, you will love this roller. Kids loved the freedom; parents loved discovering this unique, innovative and soon-to-be indispensable product.
