Tranquility Essential Booster Pads offer a capacity of 5.3 oz/157 ml. They are used as a booster pad to add absorbency to any disposable undergarment. The soft, flow-through pad fills to capacity and then passes additional fluid into the primary undergarment. The pad is secured in place by an adhesive strip where extra absorbency is needed. Latex-free. Absorbent capacity is 5.3 ounces.
