1 Inch 25 Pack 1" Tall x 1" Wide 25/Pkg White

Three stars because the magnets work well and you can write and erase them. The erasing is the problem. The magnets do not come clean with a plain rag or with using white board cleaner. I am using Expo dry erase markers and cleaners - not a generic cheap marker. After the first use the white stayed gray and won't come clean. I am using for scheduling so not end of the world but a bit disappointing.

In the image you can see an unused and used once side by side.

great magnets
