Four black corrugated plastic flexible drain pipes.
All are 10 ft. sections, and all in very good condition.
Three are the same type and have a larger collar at one end so they fit together. Nominal 4" diameter - I think that's I.D.
The one on the left in the photo is slightly smaller diameter; maybe 4" O.D., and is perforated full length.
I also have a straight 10 ft long 4" PVC drain/sewer pipe, type 2729.
