We are often asked what can go in the shredding. Paper clips, staples, files folders, coil ring notebooks are all fine as are small black binder clips. Things that are not so good are large pieces of metal, plastic bags and plastic report covers. 3 ring binders and shannon file binders need to come a part. If you have a large quantity of binders or shannon files please contact us and we can give you a quote to take them apart and shred the contents.
