There’s probably and infinite number (even if “infinity” is not a number) of these on the internet, but most of them are difficult to download or edit. This is why I created this, you can instantly download it, you can re-size it, the background is transparent so you can add easily some background. The top, bottom, left, right grunges are all separate layers.
