No raking, no replacing, no weeding, no problems! Earth-friendly recycled rubber is mixed with a bark-colored binder and placed in special molds to create edging strips so realistic you"d swear it was natural mulch. Air and water can still pass through, but weeds are blocked. These 8ft L x 4 1/2in W x 1/2in D strips are easily cut with scissors or a utility knife to fit around your planting beds, along driveways and walks, even curves. Built to survive string trimmers and mowers for lasting good looks.
