Good for the interested people.

Parents of the children who are interested in science must gift this to them as soon as possible. The poster is big and a hard sheet can be attached at the back from some local vendor who works with frames and then it can be put on wall for immediate reference. For the manufacturers, one request is to include the use of the elements too. Like by symbols it can be shown that argon is used in welding adjacent to the element argon and so on
