This is the bluish-background holo Rotom card from the POP 9 set. I have a ton of these! It is card number 5/17.
Each Rotom went right from the pack to a soft sleeve and hard toploader for protection, which is how they will ship to you through regular USPS mail. Feel free to take some of these off of my hands!
Sorry if the background doesn't look very holo-ish in the image. Each card is the holographic version popular in the multi-pack sets, not the regular version.
