I am selling pre-poured concrete cylinders with a rebar handle in the top of it. Each one weighs a little over 100 pounds. There are many good uses for these. They can be put in the water in a lake to tie your boat off to, they can be used to tie off your pets, horses, sheep or what ever animal you want to keep in one spot but yet very movable. Use your imagination. I have about a dozen of these.
