Office organizers, these PATIKIL binding bars are such a simple but brilliant solution for keeping documents together! You get 50 purple binding bars in this pack - plenty for all your office needs. Each bar is 305mm long (about 12 inches) and 10mm wide, specifically designed to hold A4 size papers. The capacity is impressive - each bar can securely hold up to 70 sheets of A4 paper without slipping. The plastic construction is durable but you can even cut them with scissors if you need custom sizes. The non-slip surface treatment is genius - the bars grip paper firmly but won't scratch or damage your documents. Using them is so easy - just align your papers, insert the binding bar at an angle, and slide it to the bottom. They're perfect for reports, presentations, resumes, homework, or any documents you need to keep organized and professional-looking. The purple color makes it easy to color-code different projects or clients. Much better than bulky binders or annoying staples that damage paper. They're reusable too - just slide them off and use them for new documents. Great for offices, schools, home organization, or anyone who deals with paperwork regularly. The clamping force is strong enough that even thin documents won't slip out, but not so tight that you can't add or remove pages. Such a simple idea but so effective for everyday document management!
