AGORA Write-On Red and Yellow Soccer Referee Card Set

Easy to use, good in wet weather

I have used these cards for approximately 200 games over the past two years and they are still working perfectly. I don't know what kind of industrial-grade cleaner these other reviews are using to clean them with that destroys the lines, but they are doing something very wrong.Ultra fine-point permanent markers and 70% isopropyl prep pads work perfectly. If the pads don't clean everything off, use a dab of hand-sanitizer.

Much better than OSI's product - better quality!

Grid lines/box border lines do not last one clear wipe away of writing. They aren't laminated so the black paint lines get rubbed off when any of the recommended cleaning methods used to remove the permanent ink. Pretty blatant design flaw.

I use a permanent marker when I ref, and when I clean it off with alcohol it takes the lines off of the card. In the description is says to use permanent markers on the card, so it seem silly that they advertise for this when cleaning the marker also destroys the lines on the card.

I was concerned about the lines rubbing off due to other reviews. I used your regular sharpie as recommended and then went out and bought a spray bottle of about 70% rubbing alcohol. If your wife or girlfriend has any makeup wipes those work good as well. Do not use nail polish remover??? I am astonished to why that was even trialed. First time I used these I felt naked without a book in my pocket. I guess they have to change the saying to you'll wind up on the card!

Really usefull
