Bait can and fishing float set

This is a set of bait cans and a fishing boat.
The manufacturer is unknown (possibly Oone), but I believe it can still be used.
How about this product for those who want to start Ayu fishing, or for those who want to reduce the risk of bait can theft during Ayu fishing expeditions?
The color is not conspicuous, so I think it is ideal for soaking in the river overnight.
The product has scratches and dirt, but as far as I can see, there are no cracks or other issues that would affect its use.
No claims, no returns, please.
