When you buy MBM® Destroyit® Shredder Bags online you are adding a convenient way to clean up shredder waste, potentially eliminating spilled shred particles. Without a shred bag in your paper shredder, you would have to pull out the waste bin and carry it to the trash - since they don't have lids, waste could spill over the edge or get blown out, creating a mess. With a shredder bad, however, you can tie the bag shut and eliminate that hassle. MBM shredder bags are compatible with several Destroyit® shredders including personal, deskside, office models and more. The bags are packaged with 100 or 200 pieces per box.
