BoBo_Bottle Board / product

BoBO has the advantage of providing drinking water and swimming training to poorer areas where drinking water is supported.
You can combine BoBo's bottle head with the bottom of another bottle to make a swimming secondary kickboard, cut along the perforated of the cover, and weave into a swimming textbook.
Secondary kickboards can be combined with each other to make stable swimming exercises, and you can learn survival swimming and swimming through the textbook. If BoBo is commonly used, it will save a lot of life in poverty.
