Target of gas can / gas can

Butane gas or spray cans require special attention when discarding them. These gas cans must be pierced to completely discharge the remaining gas before discarding. Despite knowing this fact, many people often just throw them away without such procedure. They feel inconvenienced by having to make a hole using tools such as a drill. The purpose of the design is to print target board image at the bottom of gas can to induce user affordance. The design has been added with a small fun of scoring one's action for safety and environment.
