The water bubbles are large and the amount of air is also large.
I squeezed it with a branch valve on hand, but even though the amount could be adjusted, the size of the water bubble did not change, so it was very different from the image.
Moreover, it discovered that it is sold at a price of about 1/3 to a nearby home center, it is a big shock ....
It would be fine if a fish resistant to water current would be fine, but it seems that there will be no turn in the house.
Because I broke the stone of Bukubuku, I thought about buying a bukubuku but purchased only a stone because I found a stone only item. Utilized by taking Tanaga (shrimp). It was nice to be able to take it back home and stay alive and eat fresh.
