This winter I purchased roughly 33-35 boxes of Clipstone rock for my fireplace from Menards. We love the color, style, and the feel of real stone (concrete base). It's also super easy to install -- NO GROUT/CONCRETE required. It could be used for outdoor siding or whatever as well.
I am selling because after opening the first two boxes, I realized that my fireplace is 21 feet tall. 6 feet wide and 2 feet deep. Because it's on the second floor, I felt it might be just a little too much weight for my floor, so I am going to scrap my plans and put in some light weight material like wood or other material on instead.
Menards wants a 10 or 25% restocking fee. Thought I would try to sell here first. I paid $73/box. Each box will do 5 sqft.
