A toner hopper seal-insert and slide-seal to provide for the shipping and transporting of a refilled toner cartridge. The seal-insert is comprised of two slotted rectangular strips or pieces of material. A middle piece or layer of a resilient two-sided foam tape is sandwiched between the two slotted pieces, holding them together such that their slots align. The tape is configured such that it also has a slot which is wider than the slots in the two outer pieces and open at one end, providing a channel for the slide-seal. The seal-insert is attached to the toner hopper of the toner cartridge, and the slide-seal is slid into or out of position in the seal-insert to seal or unseal the opening of the toner hopper, creating a reusable leakproof seal system. For ease of placing the seal-insert in the toner hopper, the ends of the outer pieces opposite the slot opening in the tape layer may be bent and fused together, then cut into a shape extending to a point. The slide-seal may be a magnetized flexible strip so it attracts toner and further improves the seal. It may also be provided with a handle for ease of operation. For toner hoppers with wider openings, the width of the seal-insert is increased but the slots remain the same size. The increased width of the seal-insert is furnished with a removable tool to keep the seal-insert rigid as it is placed into position on the toner hopper.
