SCHOOL MIRRORS - A6 Size - Set of 10 - PLASTIC - 6" x 4" Really handy set of SCHOOL MIRRORS. Set of 10 plastic mirrors, A6 size - 1mm thick. An essential basic piece of apparatus for investigating symmetry. Also excellent Early Years resource - Use this set of 10 acrylic mirrors to encourage children to observe the movements of their mouths when making sounds.
