Designed for mixing small batches of concrete, it can also be used to mix fertilizer and amendments, compost, paint, and more. Easier than mixing in a wheelbarrow, without the mess. The lid is used to measure water for mixing with dry concrete. Its patented design moves ingredients back and forth for the perfect consistency. Easy to use, handy to pour, a snap to clean, and compact to store. Heavy-duty polyethylene construction is rugged enough to withstand regular use. 18" x 12" diameter, 7-gallon capacity. In very good, lightly used condition - it was used to make a few stones using a Quikrete Border Maker mold.
