Review on 🛠️ Pro Project Supplies 8 Inch Composite Shims, 24 Pack - Never-Rot, High Weight Capacity, Weather Resistant. Ideal for Door, Window, and Shed Projects - Easy to Snap & DIY Home Improvement Levelers. by Joshua Turner

You worked like a champ. I had an old Rubbermaid storage shed that came with the house but closing the doors was always a problem, obviously the original installer didn't follow the leveling instructions. I collected 5 of these villains and put them in a 5# slide. And now the barn is level enough that the doors can be closed, that's a big savings or a lot of work to move and re-level a 15 year old barn that I end up spending a few hundred dollars and more to replace would. Visible from the outside, the material is good for the environment and doesn't rot. Overall I give them 10/10, exactly what I expected and worked as described.
