Concrete Stamps - River Rock Form Liner
These are interlocking form liners that can be used to create fire rings, fountains, pillars, and walls. Two of the half tools (FLRR100H) can be used so that the rocks can interlock. Otherwise to have a flat top you would use the Full tool and the half tool and it would be 27" tall.
FLRR100F (Full Tool) 18" X 40"
FLRR100H (Half Tool) 9" X 40"
