【New, Unopened】Medaka Fish Tank Set 300

Thank you for looking.

I purchased this new online a few months ago.
I am selling it because I don't have the opportunity to use it.

There are no noticeable stains or damage, including the packaging.

Medaka Fish Tank Set 300
A set for raising medaka with a gentle water flow.

I plan to wrap it in bubble wrap and ship it via RakuRaku Mercari便 (Takkyubin).
