Have a couple hundred of these thick tubes that are great for material storage when laid horizontal.
14" inside diameter/15" outside diameter by 5' tall. 1/2" wall thickness.
Selling at $5 a tube . will not ship unless you set up a truck to pick them up on your dime.
Will not collapse even with 10 rows on top of them.
Came from the old Hugo Boss suit manufacture here in Cleveland and this was the way they organized all of their fabrics.
