The volumetric elements and A4 frames are made of everlasting and hygienic plastic. Dyes (Ampaset, Belgium) are added into the plastic during the casting to keep the colors bright. Each lot of raw material has certificates. The Product itself is not liable to certification. Due to great amount of elements we can create the national assortment on the base of Display Systems “NATIONAL”. All the plastic elements are packed and can be delivered to any part of the world without any damages.
