Bloody Bathroom Accessories
Sure you could probably make these easily on your own, but as one commenter here puts it:
What about really busy people who have no time for buying acrylic craft paint, but they do have money to buy bloody bath accessories? People outsource all kinds of tasks for all kinds of reasons. This is just that point in our culture's evolution when we stop making bloody bath accessories at home, and start letting professionals do it. Just like we did with house building, dvd-player-assembling, and floss-making.
