PROBLEM TO BE SOLVED: To provide an envelope for recovering a recording liquid cartridge, which facilitates the return of the cartridge by a user and prevents the cartridge from soiling other transported articles when the cartridge is recovered using a means of transportation. SOLUTION: The envelope 1 has a two-layer structure consisting of an inner layer 11 capable of absorbing the recording liquid and an outer layer 12 having waterproofness, or has a three-layer structure consisting of an inner layer 21 capable of absorbing the recording liquid, an intermediate layer 22 having waterproofness, and a writable outer layer 23. The envelope 1 has a sealing part 3, and a part 5 of an envelope body 2 is extended across a reference line 4 to form both ends of the sealing part 3, which prevents a leak of the liquid from the enclosed ink cartridge 101 to the outside.
