1-2 Punch packs a good punch!
Review by Jodi G. on 24 Sep 2024 review stating 1-2 Punch packs a good punch! The punch works nicely to round corners. The blade is sharp and the spring is tight. The notch corner works much the same, although is meant for envelope design and not the card itself, I believe. The tool is simple but effective.
