I have one single pole unit for the Stolmen system. Comes with pole, brackets, instructions, tools, and probably all the hardware minus drywall anchors.
It was a diy cat scratching post/tower system for many years, so there are some very minor scuff marks and scratches, maybe a little discoloration of some of the plastic parts, and a few holes where I needed to add some screws into the pole itself. Still sturdy and sound.
Just let me know that you want it and I can set it outside for you to pick up at your leisure.
