I use a dry erase board to keep all the activities for my family every week & I usually have to replace my markers every month or so but these are really different, they don’t dry out as fast and the colors are more easy to differentiate. I would definitely recommend these markers to all the moms I know to keep up with their family activities and to my friends who are teachers who go thru bookoodles of dry erase markers. They write smoothly & are just a really good product. The only reason I didn’t give them a five is because the markets easily slip out of my fingers. They might want to reconsider the way the markers are made for that reason, otherwise they are a great product. Thanks to #influenster for the markers in exchange for my honest review!
