This Japanese stapler owes its onomatopoetic name to the sound it makes when carrying out its task: ga-chuck. It is an effect that almost domineers the soundscape of Japanese offices. The housing of the stapler is made of plastic with a magazine of 16 mm wide staples. With the aid of a sliding mechanism, the staples are advanced to the exit opening one at a time. Each one staples together up to 25 sheets of paper. The staples hold the sheets firmly but can be easily removed like paper clips. They won’t damage the paper, and they can be reused. If you use them in pairs of two or four and put them on the side of a stack of paper, they can provide a temporary i.e. removable binding.
