All right, I myself am not quite sure what to make of this when it comes to the name, considering how everything is in Japanese and the words are embedded within an image file, which means Google Translate would be rendered as useless. It is a good thing that a picture speaks a thousand words, and this is why I more or less speculate that what you see here is a Disney Water Bottle Cap Pen. Basically, all you need is an empty water bottle (preferably that of a 1.5 liter capacity), and all you need to do is remove the cover, fill ‘er up with water, and then screw on the Disney Water Bottle Cap Pen. Turn it upside down, and a steady stream of water will be released, just enough for you to “draw” on hot sidewalks with water. Needless to say, the artwork will be there for just a while before the wonders of evaporation kick in.
