This lovely round 10cm 'Tree of Life' ornament was very popular in our recent 'pop up retail shop'. It seems to be a thought provoking symbol for many. It's 2mm thick and has a hanging hole.
If you want to display it outside we'd recommend a painted version (as mild steel will eventually rust but not deteriorate) or even spray painting it yourself to match your home surroundings.
We'll post our painted versions soon, or message us and we'll send you a pic.
