I always thought C-3PO was sort of a dick to R2-D2. He was always smug and giving R2 a hard time even though R2 turns out to know best most of the time. Still, they are best friends, so go figure. If you have a bestie and you need a gift for the holidays here is the perfect thing.
The two necklaces together make a heart and each half of the heart is printed with one of the droids you are looking for. The necklaces are made of stainless steel and on the back it says “Best Friends.”
You can get the heart necklace for $12.99(USD) at ThinkGeek right now. Just be sure who ever is the bossier, more dickish friend gets the 3PO half.
