I was very impressed with this set. However, it just did fit my Big Shot (lemgth-wise), but in all fairness, I wasn't using the extended base that came with my Big Shot.
Anyway, the dies cut really nice, and the create beautiful images. I love these! I only had 1 issue, and it was probably the operator's fault (me). The die tends to warp just a bit when I run it through my Big Shot. It straightened out fine though.
The best part I love about Pink and Main dies are 1. They are already cut apart
2. They are Pink! I can spot they from any other dies I have. And....
3. They have ALWAYS cut clean for me!
