Torayvino Replacement Cartridge STC.J Set of 2. Brand new, unused. 1500-liter type. I bought these as a set, but I've been storing them after taking them out of the box, so this listing is "without the outer box," but the items themselves are in good condition. They are individually wrapped in plastic. I will pack them carefully and ship them. Immediate purchase OK! Please comment if you have any requests, and I will try to accommodate them.
