This set of 3 includes The Original Olaplex Hair Prefector (8.5 fl oz), Olaplex Bond Maintenance Shampoo (8.5 fl oz) and Olaplex Bond Maintenance Conditioner. They were purchased recently from Sephora but never used. They are all in brand new condition with the seal intact. They are full size, not sample size, at 8.5 fl oz each so will these last you awhile!
