    I am sinking posts into the ground. Can the tubing be left on, after the concrete dries? It will be underground and be out of sight. I will be compacting the earth between the posts.

                              These 10" cardboard tubes were just what we needed. We cut them into 4' lengths and painted them brown, and used them as columns to set a potted plant on, for a special display we were setting up. They're not just for concrete anymore!

                              Purchased these to make part of the stage set for VBS at our church. Drilled holes and connected with zipties and duct tape, wrapped in paper and painted to look like a tree trunk. Very sturdy and lasted all week!

                              Works well, but the tube ID is not 10" any more. I have previously used these and made positioning frames to hold the tube in place. The brackets wouldn't fit the newly purchased tube. They are actually 10 1/2" ID, so I had to remake my brackets. More inconvenience than problem, but the product changed dimensions.

                              This is a simple way of installing fences post and similar configurations to insuring efficient use of concrete. Additionally form tube can be adjusted to shape the cement form to desired configurations for a larger base/top, or a larger center as required.

                              Unfortunately I have to give these tubes a bad rating because the diameters were NOT accurate. One tube was 9.25 inches in diameter and the other was slightly bigger than 10 inches. For my purposes they needed to be exactly the same size. I ordered online, which was a mistake. Definitely go to the store to pick out the tubes if this is a consideration.
