These were placed I the new teachers "survival" kits. I have gotten good feedback about how they erase and it is so nice just to leave them on the board.Used these in my classroom a whole year and they were still in great shape at the end, so the kiddos were each able to keep them and I reordered them again for the upcoming school year.There are a lot of erasers for the price. Definitely a good purchase. So far they have held up well, but we've only used them two days. lolPerfect value for the moneyThe markers never last long. I really like the magnetic erasers though. It just makes them so much easier to store away and to access for my students. I do need to figure out how to clean them though. Other than that...pretty good buy.I bought these for my classroom, and they work great for dry erase boards. I did have some students write on the back of them, and they were forever graffitied. The magnets are very good. The erasers lasted a school year, and will probably last one more. I would recommend these to a friendErasers are good, markers are horrible. I chose these because of markers, so I may be returning.Sturdy enough to handle my 5 and 6 year old students. They fit perfectly in their little hands. They did write on them and I was unable to remove marks but they still work! Great value and now students no longer had to share supplies.
