All-purpose Stand for Koinobori (Carp Streamers)

This is a versatile stand for Koinobori (carp streamers).
If you wish, I can also include the pinwheel from the third photo and the pole to raise the Koinobori higher!!

Please note that the strings and Koinobori themselves are not included.
An unused water bag is also included. I believe it is usable, but it may be deteriorated.

The stand itself should still be usable, but please refrain from purchasing if you are looking for a perfect item as it is a used product!
