These MAS 275 waved paper clips are designed for securely fastening documents in an office, school, or home setting. Each clip measures 70mm and corresponds to size №7, featuring a corrugated shape that provides a firmer grip on your papers than standard smooth clips. Made from metal with an anti-corrosive coating, these tools are built to resist rust and maintain their integrity over time. They come in a convenient cardboard box containing 20 pieces, making them a practical choice for those who need to organize thicker stacks of pages without damaging the sheets.
