Each tube expands to approximately 4 feet in length and is 12 inches in diameter, has a crunchy, plastic liner and can easily be attached to another 4-foot section simply by compressing the end of one tube into another for endless additions. Tubes are hand washable simply by dunking in a sink of sudsy water, rinsing, squeezing out excess water along tube's circumference and hanging up vertically to drip dry.
All tubes now come with black interior.
