It’s important to always keep a supply of shred bags on hand. Old, worn out bags or thin, flimsy bags are no substitute for real, reinforced shred bags. Don’t wait until you’re cleaning up the mess left from a split open bag. Trust Whitaker Brothers to have the right size bag to fit your MBM-Destroyit shredder. We offer the Whitaker Shred Bag Guarantee, if this bag does not fit your Destroyit 4000SS shredder, then return it for a full refund. And don’t forget our WBBM-55 shredder oil available in convenient pints or economical gallons, for maintaining your shredder’s peak performance.
