Improved Life Buoy / buoy

Improved Life Buoy
Improved Life Buoy

It's hard for traditional life buoys to be stacked in good order because their smooth surface will let them fall on the ground.But these nested structure can be connected and fixed with each other and it is easy to transport them. One side of the buoy has groove, and the surface of the other side is convex. So, it's easier for users to grasp the life buoy to save their energy.
The composite material of foaming and rubber can increase the friction in order to be stacked in good order. Rubber will also increase the buoy’s tenacity and durability, so it’s easy to connect and separate them and buoys won’t be easily damaged by external force.
