Made of thermoplastic polycarbonate, it has strength, flexibility and durability. The high point is that it extends the life of the wall and the need to maintain gravity. The smooth and round design makes it durable, prevents the breeding of dust mites, and is easy to clean. It can withstand high temperature and humidity of 100 degrees, thereby preventing shrinkage and long-term use loss. The wall thickness is perfect and it is easy to place on the grid. Constantly cleaning the walls helps to decorate the visible patterns.
