If the whole including the Handmade Sink with 4mm slot body is actually unnecessary, there are two main reasons:
First: The 1.0mm thick water tank is enough to use until the next decoration will not be damaged, unless it is intentionally damaged. 4mm undoubtedly increased the cost of production, it is not as good as this cost is used in other configurations of the sink.
Second: The elasticity of the wall of the 4.0mm thick sink is too far from the elasticity of the 1.0mm thick sink, so there is no benefit to the bowl and the main body of the sink.
But if the edge is 4mm and the groove is 1-2mm, this design is better. why?
First of all, the 4mm edge can carry a large weight of the water tank, and the tank body will not be deformed for a long time, and it is very flat. The sink wall is relatively thin, so that the dishes will not be hurt. Therefore, it is recommended that the preferred edge is 4mm, and the tank body is 1-2mm.
