The Staple-less “Stapler” may not be an accurate name. It is a small paper binder that makes small cuts and folds in two or more paper sheets, creating a tucked loop that holds the sheets together.
The main negatives I can see are that it isn’t good for too many sheets, and it isn’t as permanent as a stapler. But on the plus side, it won’t cut your finger, it doesn’t need staples or any other type of refill, there is no rust on your documents after time, and it’s cheap, lightweight, and portable. What’s not to like?
I got one a few months ago, and have found it to be a reliable and useful desk accessory. It is perfect for quickly attaching a few pages.
