Even if I had a million dollars, I wouldn't shell out the cost for this set.
In this case, you really are paying for the artwork rather than the vibrator itself, which I find... rather pointless. I understand getting one of these if you are a fan of this particular artist, which I'm not (there are other more attractive Western cartoon styles in my opinion), but not an entire set unless you really love to collect them. And then not even use them on top of it, being metallic paint and all? Just... completely not worth it, in my humble opinion.
Don't get me wrong, I love and appreciate artwork to the fullest, but to me, making character designs and prints for toys that are supposed to be enjoyed for more than aesthetics alone purely doesn't make sense to me. They are two mediums that don't do much for each other but look pretty. Now, if these were silicone toys that had grooves of the characters or their prominent features were used to give a unique texture, that would be another story, but they don't and are there only to be visually appealing on a toy, and likewise, an "art form" that is significantly more functional in nature, and ultimately, purpose.
