Penis extender/sleeve recommendation

Hello I’m trying to buy a penis extender/sleeve for my girlfriend and I to use as she would like some more length mostly and extra girth wouldn’t be to bad. I measure to be 5 inch length 4.5 circumference 1.43 diameter. We talked and she wants to mostly length added but isn’t sure how much more as I am her first. She would like a sleeve that is shaped like the real thing to start with. I’m not concerned with price but I am concerned with what material it’s made with. I’d rather us have a safe material toy. We are purchasing/shipping to a United States address. What toys do you recommend for someone to start with?
