We now carry 10 different sizes of tubes. All our tubes are spiral wound with your color choice of red, silver or natural Kraft. Standard or extra heavy walls are available. We are very proud to offer the best selection and lowest prices available on all of our products. All our tubes and plugs are weighed on very accurate digital scales, not counted. So you may be 1 or 2 over or under. Check back often as I'm always adding new items.
