Fiskars Corner Lever Punches are great for taking to crops because of their compact size. Features include: lever driven punching for creating fun shapes, built in confetti catcher helps keep work area clean, great for layering with larger shapes in the line, and white paper guides help paper get to the right spot for perfect corners every time!
This punch makes extremely smooth, beautiful rounded corners, and the best part, is that it's fool-proof - you can't not get the paper in right, the guides ensure a perfect corner every time. Awesome. :-)
