These are the original hard drive spacers/insulation for a 3rd Generation iPod. These parts create a nice snug fit inside the iPod, while protecting both the logic board and hard drive from damage. This is for the thick models only (30gb, 40gb). For the thin 10gb/15gb/20gb models it is a different part, check my other listings. 

These are genuine parts pulled from a used iPod. They show some light wear but are in good working order.
