Silhouette America - 12 x 12 Media Chipboard

Extremely thin but workable

I would not call this chipboard. It's roughly between real cardstock and real chipboard, and it's a sort of a grey color, not the kraft color I expected. However, it held up decently in cutting and after being painted with acrylic, and there is a setting for cutting exactly this stuff in studio (no surprise, really, but it's an extra layer of mat/blade safety when you don't have to guess). Honestly, even though it's thin, I'll use it again.
