I've had these stuck to my fridge for about a week now. I have had no issues with the sliding or moving around when I put markers in or take them out. They hold about 4 of the larger expo markers and 8-9 of the smaller fine tip ones.

These dry erase holders aren't half bad - they're just very small. The pictures are accurate, and these holders will only hold 3 standard dry erase markers. If you have smaller markers, it'll fit a few more. The holders themselves are sturdy enough, made out of thick plastic, and the magnets are strong enough to hold them in place anywhere on my dry erase board. I just wish they were bigger.

These slim dry earse holders are pretty good for classroom use. They do have some pros and cons. Pros, the white appearance blends into any magnetic whiteboard design perfectly. The magnetic hold is really strong to avoid from falling or sliding down the board. It is great in holding up to 8 skinny dry earse markers if needed. The only con is that its slim design doesn't leave much room for thicker dry erase markers. I was only able to store 3 large expo markers, verse being able to storage up to 8 of the skinny dry earse markers. Overall, these are great for having items easily accessible.

I have one of these on my fridge, and one on my file cabinet. Strong magnetic grip - the magnet on the backside runs the entire height and width of holder. It holds about 3 fat expo markers. It is NOT big enough to hold the dry erasers. It will also hold about 8-10 ballpoint pens fully. However, if you only have 2 or 3 in there they fall over. The holder is not tall enough for pens to stay upright. I will not attempt to try scissors. The one on my fridge is a good size to hold a few pens and bottle openers.

This organizer is intended for whiteboard and refrigerator surfaces. The back of this case is entirely magenetic so it stays put on the refrigerator like shown in my video. No mess or sticky residues left when it is detached later. Also, it helps me not to lose my markers and erasers and keep them in one place. It is useful for both home and classrooms, and a basic organizing item to keep the white board area clean and neat. Also, if you have a shared classroom, it is easy to detach it and bring back in your caddy. Each holder can hold upto 4-5 markers. and this set has 2 identical cases, and the color is white.
