Tired of loose papers everywhere? These simple spine bars (or clamping rails) are an office classic for a reason. This pack gives you 25 blue plastic bars designed to hold together stacks of A4-sized paper (that's your standard letter-size in many places). Each bar can clamp about 30 sheets, which is a filling height of up to 3mm. They have rounded corners so you can slide your papers in easily without tearing. The best part? They come with pre-punched universal holes along the spine, so once you've clipped your documents together, you can file the whole bundle neatly into a ring binder or lever arch file. Each bar is 30 cm long to fit A4 width perfectly. They're super basic but incredibly useful for organizing reports, presentations, schoolwork, or any project papers you need to keep together and portable. A pack of 25 means you'll have plenty on hand for multiple projects. No-fuss, practical organization.
