From the field to the palace
Format: Paperback
Very good read. I recommend it. David was GOD'S KING. He wanted to build GOD a temple, but couldn't. It took another king to build David a palace, because he probably would have built himself a shack. That's where he came from. A good read

Solid, stable, good-looking and functional
Color: Silver
Feels solid. Suction cups hold it firmly to the counter. Tension arm allows smooth unrolling of the paper towel while holding the unrolled portion firmly for easy tear off. Perfect for our motor coach.

Ohana caregiver
Color: Black
Its sturdy/heavy and the suction cups on the bottom work well. Our family is able to pull the paper towel without pulling the whole holder with them. The arm that holds the paper towel works well and we can pull one towel at a time. We are very happy with this product.
