My family is loving these magnetic whiteboard erasers! They are so much fun being the emoji designs. My youngest is a HUGE fan of the emojis so he was ecstatic to see them when they arrived. We have one on the fridge by our calendar there. And we also have a few on the whiteboard we use for our homeschool lessons. A couple of my children, who use personal whiteboards frequently, each have one with their school supplies. They erase the dry erase markers with ease. The only problem I encountered is the fact that I forgot to erase some work off the whiteboard before we took a week break so that did not come off easily but that was to be expected. Highly recommended!!
