Calling all soccer referees and coaches! This InnoHHustle referee cards set is exactly what you need for managing games professionally. You get 10 cards total - 5 bright yellow warning cards and 5 red ejection cards, so you're fully equipped for any match situation. Each card measures 11x8cm (that's about 4.3x3.1 inches), which is the perfect size - big enough for players and spectators to see clearly, but still easy to handle and store in your pocket. They're made from high-quality PVC material that's seriously durable and wear-resistant. The surface is smooth and comfortable to hold, and they won't easily bend or deform, even if you're using them game after game. What's really handy is that they're waterproof and sweat-proof, so if you're refereeing in the rain or on a hot, sweaty day, these cards will hold up perfectly. The edges are smooth too, so no worries about paper cuts or scratches. They're lightweight and portable, making them easy to carry with your other referee gear. Whether you're officiating amateur matches, school games, youth leagues, or even more competitive matches, these cards will help you maintain control and communicate clearly with players. The classic red and yellow colors are instantly recognizable to everyone on the field. They're basically the referee's best friend when it comes to managing game discipline and keeping everything fair and organized!
