This iron-on number set is absolutely perfect for customizing team jerseys or personal projects! You get 22 pieces total with numbers 0-9 and some letters, all about 8 inches tall - perfect size for sports jerseys where you need visibility from a distance. The PU material is durable, flexible, and won't fade or crack easily after washing. Application is straightforward - just iron them on at 284-320°F for 10-15 seconds with pressure, let cool, then peel off the backing. I used these for my son's soccer team jerseys, and they held up perfectly through multiple games and washes. The black and white colors are vibrant and professional-looking. The package has enough numbers that you can do multiple jerseys without running out. If you're tired of paying for custom printing or want to DIY your team uniforms, this set is absolutely worth it. They're much more affordable than professional printing and give you the flexibility to create any number combination you need. The quality is really good - no peeling or cracking even after heavy use. Definitely recommended for sports teams, school projects, or any DIY clothing customization!
