Normal Sonic Toothbrush have more cleaning power than a battery powered sonic brush. Normal Sonic Toothbrush also not require any changing of batteries; a user would only need to charge the toothbrush(when there not using the brush or when the brush battery is dead).
Bro imagine what a badass some kid would be if they just walked into school with their blendy pen scroll and just unrolled that shit to show off their collection

When I was a kid, I didn't see the point of these. I always preferred to make drawings with colors that didn't blend into each other. I didn't think of gradient colors as very useful.
