I really like them but I'm glad that I read the description that you have to double it up to get the same thickness as the ones that come premade in a kit.
These are really great to keep on hand!! I can cut what ever I need to go with my kits!!!
This product allows you to keep using your dies without buying the refills but rather cutting your own. Also can you other dies.
The foam is not my favorite,the acetate sheet are great. But I am just learning and I'm sure there is a curve.
