1lb Propane Bottle Labeled Caps

Note: This is not intended to stop leaking containers. If your container is leaking, bring it to a well ventilated area free of fire or sparks. In my constant battle of trying to figure out which containers were new, used, or empty, I made these to visibly show the state each container is in. A knurled texture is added for grip, and text is added to show the state of each container as well.
