No, I have shipped a lot of axles, springs, radius rods, etc and just put bubble wrap over them and then tape the h*** out of it with clear tape. Haven't had any problems so far, although a clerk at Kinkos (FedEx outlet) wouldn't take something one time, but I went to UPS and off it went.

The hairpins were in cardboard. I first wiretied them together, wrapped them in bubble wrap, and made a box that was tapered sort of like their shape. It was 39 inches long, x 8 wide x 3 thick, kinda tough to miss.
