A true must for everybody who mixes shampoos. Mixing bottles saves you money. Plain and simple you mix and use only what you need. 32 oz. Bottle fits in the palm of your hand; graduated from 1:1 thru 20:1 and good for any concentrated product. A smart product that will pay for itself over and over again!!! Get ready for the day by premixing your bottles. (Mixing bottle replacement top only).
