AGORA Write-On Red and Yellow Soccer Referee Card Set

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.

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.

Really usefull

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.

Much better than OSI's product - better quality!

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!

PERFECT!! Just make sure you have a dry-erase marker for easy cleaning.

Trying to find a write on card that works and this one doesn't. The one nice thing is that it's not laminated which eventually peels and separates. Tried the card with permanent fine tip sharpie as shown and then immediately went to write it off with 70% rubbing alcohol (isopropyl) and the lines rubbed off with it. I saw some people saying try denatured alcohol (ethanol) so I tried that a few moments later and that safely keeps the lines intact but it doesn't completely remove the permanent marker as shown in the picture. I can't find anywhere here in the Amazon description details or the Sator site specifying ethanol should be used so that would have been helpful. Of course any humidity refers a permanent marker useless.It was only 4 bucks, 8 with shipping so not worth shipping back. Moving on to the next card to try
