Dr. Hydrogen Bottle, New, 2 Cannulas Included, Original Box Available, Upgradeable to Newest Version

Selling my Dr. Hydrogen Bottle as I've purchased a professional-grade hydrogen inhaler for home use.
(I still use one of these for when I go out and love it!)

Purchased from an authorized retailer.

I have regularly performed citric acid cleaning.

There are no major visible scratches, and both the 5-minute and 30-minute modes operate without issue. The hydrogen generation amount is also excellent, and I believe it can still be used for a long time.

The battery life is also good.

The Dr. Hydrogen Bottle is said to have outstanding performance among portable hydrogen devices.

Includes two new, unused cannulas.

While I believe it is still usable, as it is a used item, I recommend having it professionally maintained by the manufacturer after purchase to restore its hydrogen generation capacity to like-new condition.
(I can also assist with arranging this maintenance.)

For reference (shipping not included for either):
◉ Paid Maintenance: ¥26,400~
　→ Battery, circuit board, and electrodes will be replaced with new ones.

◉ The new Dr. Hydrogen+ model has been released, and you can also upgrade this bottle to the new model when you have it serviced.
　→ Upgrade: ¥60,500~

As this is a used item, please no claims or returns.
