Maintenance sheets specifically for shredders, containing oil. Compatible with A4 and A5 input widths. Suitable for shredders that can cut 2 or more sheets at once. Simply shred the sheet to easily maintain the cutter blades. The oil lubricates the cutter surface, preventing a decline in cutting performance and reducing noise. There are 10 sheets remaining out of 12, so I am offering them for sale. Would anyone like to use them?
