Flexible Sink Waste Pipes

Material: The pipes are likely made of PVC (polyvinyl chloride), a common material for plumbing applications.

Flexibility: The corrugated design allows the pipes to bend easily, making installation more convenient.

Colors: The pipes are available in different colors, such as red, orange, and gray, which might indicate different sizes or materials.

Connections: Each pipe has two ends: one end likely has a slip-on connector to fit over the sink drain, and the other end connects to the drain pipe.

"1.5" marking: This likely indicates the pipe diameter, which is 1.5 inches.
