I would recommend this product to use with any die that has a fold line in it. I was forever cutting through the fold line and was not aware of this product until I watched a video by Tim Holtz on CHA! Yay! Now my fold lines are just folded!!!!
The service is great. The product arrived very quickly. I have not used it yet but I have it as soon as my die arrives.
Works very well with the spellbinders nestabilities and the Sizzix Big Shot Machine
