>>6643935>>6643923They really are erasers, they're made in the style of Iwako's puzzle erasers. I'm not really willing to ruin mine testing that, but I have heard from others that they work.
>>6643992Just be warned that they don't look as good as the promo photos or the photos on the box. Due to their rubbery eraser-like composition, they look sort of dry and dusty, and the colors are quite washed out. It's a little bit of a bummer, cause these are the cutest SD sculpts I've seen in ages. Don't get me wrong, I still think they're worthwhile--the sculpts are great, they are lightly articulated, the color separation is awesome (there is no paint on these guys!), and the part swapping capabilities are fun. I just kind of wish they'd done them proper justice in PVC.
