These nifty bastards are 4" tall by 6" wide, so it's not obnoxious (like some other MMA StickerS out there...) And they utilize the high-tech principle of static electricity to affix themselves to your window. That means, unlike stickers, you can peel and replace them in other locations should you feel the need.
You can get your grubby hands on one for only $5! (plus shipping/handling, depending on your particular part of this planet).
Sponsors and Supporting Members get $2 off their purchase!
