Difficult to notch
Like all WRMK products, this is innovative in the way it makes things easy to replicate for crafters. The punch works perfectly, though it takes a bit of time to position the tool correctly for use, but I found it difficult to notch, which requires bending the paper to align the notch together. At one point I tore my envelope trying to notch it. It does look cute when I get it to work, but it's really not my go to tool for envelope making.
