Two bottles of Redkin Color Extend Conditioner For Color-Treated Hair. Bottles state 8.5 Fl Oz e a. I weighed them to make sure. One is underweight at 7.6 oz. The other is over at 9.7 oz. Total weight 17.3 oz. (which is just a bit over the 8.5 X 2, which equals 17 oz.) I wanted to be sure you were not getting less than you expected. I bought these new, and have not used either of them. Thank you for looking at my Ebay items.
