Uses for Empty Caulk Tubes

I was doing an organizer that would incorporate using TP tubes. I was concerned that cardboard would not hold up well. So, looking around I found some empty caulking tubes my husband was getting ready to pitch. The diameter was perfect. To cut length, I used my craft scissors. These could be used for anything a cardboard TP tube could be used for.

They are easy to clean as the contents are pushed out with a caulk gun. What little residue there is easily cleans up by rinsing with hot water. They can be decorated in the same way as toilet paper tubes. Since plastic taxes the environment more than cardboard, it is another way to 'reuse' and repurpose.
