Wanta Dog Walking Water Purifier & Manner Shower 4-Piece Set Unopened

This is a pet water dispenser and etiquette shower bottle with a water purifier.
When you open the tray attached to the bottle, it becomes a water dispenser, and when closed, water comes out from the shower nozzle on the side. The water dispenser nozzle has a water purification cartridge attached.

I think it's a common problem, but bottles with opening trays tend to break at the rotating part if you drop them a little, right?
Since you can't stop going for walks even if it breaks, I'm listing them as a set of 4, including a spare.
The replacement目安 for the water purification cartridge is approximately 60 days when used at 1 liter per day.
The bottles are no longer sold, but the water purification cartridges seem to be available on Rakuten and other sites.

Convenient shower type for after your pet's toilet.

*Each box contains one bottle with a tray and one water purification cartridge.
