On Amazon, I then saw this magnetic wiping sponge and thought I must have this.
The wiper is handy. Just right to wipe from scribbled on the whiteboard.
The underside of the wiper has magnets and Velcro closures, so you can just turn the felt material when it is very dirty on the page. I find an excellent solution so I can use the sponge more often.
I would buy them to give it back.
