I am happy that American Crafts makes this cartridge. I bought the Your Story for Provo Craft and it came with a trimmer. Unfortunately, Provo Craft does not sell the cartridges for their product and many of us were a little upset. Well along comes American Crafts and if fits my trimmer as well. I am so happy that Scrapbook.com sells this.
Searched forever for replacement blades to the cutter that came as a free gift when ordering Your Story but they didn't carry the extra replacement blades! Hooray for scrapbook.com! Perfect fit!
