【Unused Item】One Water ECO Main Unit + 4 Boxes of Unopened Cartridges Set - Sub-Atomic Water

This is a set including the main unit of a Soryu Water water purifier for kitchens (unused) and 4 boxes of replacement cartridges.
It could not be installed on the faucet at my new residence, so I am offering it to someone who needs it.

[Reference Official Prices]
One Water ECO Main Unit: ￥19,800 (tax included)
Replacement Cartridge: ￥4,950 (tax included) x 4 boxes

[Product Condition & Notes]
■ Main Unit: Unused.
This unit was received through the service that replaces the main unit every 2 years, so the female adapter (part for faucet installation) is not included. If you need it, please contact the manufacturer (Free Science Co., Ltd.) directly to inquire and order it.
Although it is an unused item, it has been opened once for the purpose of taking photos for this listing.

■ Cartridges: All 4 boxes are completely unopened and new.
There are traces of personal information stickers being removed from the outer boxes during shipping, but there is absolutely no issue with the quality of the contents.
