Pure Crystal Well for Dogs, 1.5L

I tried this for 2-3 days, but my child wouldn't drink it, so I'm selling it.
It's in very clean condition. It has been washed and disinfected with alcohol, but please refrain from purchasing if you are concerned as it is a used item.
The instruction manual is also included.
I will also include the separately sold USB adapter and 3 filters (the outer bag has been opened, but the individual packages are unopened).

Please note that I will be wrapping this directly in the outer box.
