The importance of educational materials such as desks, seats, tables etc. is so important as the accessories that follows them
For example how we could use a whiteboard if we did not have the marker, the sponge or the ink.
Starting from the markers should be suitable for writing on a white table and can be refilled to have more durability and economy.
The sponges, at least those that we have are made of aluminum or wood.
On aluminum sponge can be placed felt and once absorb enough ink then we have to replace it so once again we have economy and durability.
The wooden sponge has the felt over it that connected with clue.
The inks that we use must be appropriate for marker refilling.
We must take care during the refilling procedure of the markers.
It is very important also when we realize that a marker does not write anymore on the board we must not press it by thinking that will continue to write but to fill it immediately to avoid any damage in its tip.
