I bought these to go with the Rock Star 12 x 12 papers. The shapes and colors coordinate really well with the paper. The thing I like most about these chipboard die cuts is that there is a different color/pattern on each side. It gives you much more versatility, although sometimes I had problems choosing which color I liked best!
This box comes with all kinds of different shapes and colors. There are stars, arrows, skulls, etc.. The coolest part is that they are reversible so you have two different color choices.
