This is a set of structurally robust large-capacity plastic barrel molds. The top of the mold features a wide, recessed grip handle precisely in the center of the lid. This clever humanized detail makes it easy for users to exert force when opening the heavy lid, allowing for convenient lifting even when the bin is full of heavy waste. Hidden multiple reinforcing ribs support the body of the barrel, ensuring it is drop-resistant and pressure-proof, making it difficult to damage.
