The sponge I ordered in blue + red for whiteboards at the office. Very handy, I find the inner magnets. This adheres to the sponge on the board and does not require any additional storage tray. Since he is not too large, it is more suitable for smaller tables.
The fleece on the bottom is soft and brushing Scripture well from the board, however, dissolved in one of the non-woven sponges at the edges after a very short time, so I forgive 4 stars.
