Organizing a race or sports event? This 100-pack of running bibs has everything you need! The bibs measure 7.5x6 inches - large enough for clear visibility but not cumbersome for athletes. They're numbered 1 through 100 with bold, easy-to-read printing that stands out during competitions. The waterproof paper material is surprisingly durable and tear-resistant, holding up well even in rainy conditions. You also get 500 silver safety pins - that's 5 pins per bib, ensuring secure attachment without worrying about shortages. The bibs are perfect for marathons, track meets, school sports days, or even fun family competitions. What's great is they're also customizable - you can write names, add stickers, or draw on them to personalize for your event. The quality is much better than cheap photocopied numbers, giving your event a more professional feel. Whether you're coordinating a large race or just need numbers for team practices, this set provides excellent value and reliability. The pins are sturdy and sharp enough to go through fabric easily but with safety ends that prevent injuries. Definitely takes the stress out of preparing numbers for any sporting event while keeping costs reasonable.
