[Solid Brass Construction]: Made of forged solid brass, the check valve ensures stable performance even after prolonged use. [Multiple Protection]: The plug effectively prevents odors and insects from entering the drain and prevents sewage backups. [Universal Connection]: Thanks to its universal connection, the deodorizing baffle fits perfectly into floor drains and pipes, preventing leaks and loosening. [Twice as Fast Drainage]: This filter plug uses a band structure, allowing for faster drainage than magnetic levitation plugs.
