EMOB Wooden Frame Double Sided Magnetic Whiteboard & Black Slate is a really cool slate. The white side comes with a marker to write on and a duster to erase. There are alphanumeric, mathematical signs, and tangrams for children to play and learn. The blackboard can be used to write with three different colored chalks provided with the set, and the duster is used to erase it. Kids can practice writing and mathematical sums on the blackboard and reuse it again and again. The 2 in 1 board is very sturdy and will survive under rough use.
