REDKEN Color Extend Blondage Express Anti-Brass Purple Hair Mask - 8.5 fl oz. REDKEN 5th Avenue NYC. Color Extend Blondage EXPRESS Anti-Brass Ultra-pigmented Purple Mask for super cool blondes. 8.5 fl oz 250ml but a little might be gone- I don't remember opening it or using it but there is no seal on this bottle of Redken products like my other salon sized bottles from Redken but the lid/cap is totally different as well. It's not filled all the way but I don't think bottles are ever fully filled anyways....... Please see where product sits at when bottle is in standing position- see last picture. Product smells AMAZING!!!
