This little desktop punch is way more useful than it looks! It's actually three tools in one: it creates slots for ID card attachments (perfect for those thick security badges), punches regular 1/4-inch holes for hanging, AND rounds corners to get rid of those sharp edges on plastic or paper cards. The slot punch makes those clean 9/16 x 1/8 inch slots that work with most badge reels and attachments. Meanwhile the corner cutter gives everything a nice finished look with 1/8 inch radius rounded edges. It's built solid with metal and plastic construction, and the center guide adjusts in 1/8 inch increments so you get perfect placement every time. There's even a little compartment that catches all the punch-outs so you're not left with tiny paper bits everywhere. Whether you're in HR issuing new employee badges, a teacher making classroom IDs, or just need to organize your own collection of access cards, this thing saves so much time and frustration compared to struggling with individual tools.
