How do I protect the CPU pins

I have a i7 720QM mobile processor I want to sell. These CPUs still have the pins on them - how can I secure them for shipping? Are there any pin protectors/special cases that I can buy?
 
They're not that fragile...
Just slip the CPU in anti-static baggie, and wrap that in bubble-wrap, stick in envelope and off it goes...
 
You can actually cut a small square of foam to set the chip in.

^This.

If it still has pins you really should cut a exact size square, push the cpu into the foam so the pins are protected. Then anti static bag. Make sure the bag is closed.. then peanuts or whatever.
 
It needs to be high density foam to be pushed in to. If all you have is soft foam like whats pillows are made from then just fold it over like a soft taco :)
 
Cut them all off and put them in a little baggy with a roll of solder and a note to the new owner that says "good luck :)"
 
Is the foam you guys are talking about, polystyrene foam, the stuff thats used as packing material in boxes of dvd drives and other hw parts? Is static electricity a problem with polystyrene?

Polystyrene is unsafe unless it's treated to be anti-static during manufacture. The same goes for urethane, vinyl, polyethylene, and PET.

One way to do a rough test of static generated by materials is by turning on a faucet so it barely dribbles a steady stream of water. Rub the material against something that generates static, like cotton, silk, wool fabric, etc., then hold it near the stream. The stream will bend, maybe as much as 4". Try the same with pink anti-static bubble or foam wrap or a metallic plastic bag turned inside-out, and the water stream won't budge.

If you don't have any anti-static material available, use aluminum foil.
