Philips Norelco Shaver Heads

Set of three replacement shaver heads. Features Dual Precision cutting system. Designed for a quick and close shave. I bought these blindly so I don’t know the series or type of blade but they are new & unused! So if you recognize this pattern/color/style of blade, it will work for you! Had I been able to see the other side of the heads I would’ve known it wasn’t going to work for my husband!
