Meisui Ge-1Z Premium Built-in Water Purifier Cartridge. The regular price seems to be around 13,000 yen. I'm moving, and I won't be using this, so I'm putting it up for sale. The cartridge has the film on it, but I only opened the bag because I couldn't install it myself, so it's unused. There is no box, so I will pack it with bubble wrap and cardboard to fit the size. Type... Countertop/Built-in Water Purifier Cartridge - Brand: Meisui - Model Name: GEZ - Purpose: Water Purifier Cartridge - Color: Silver
