Pica VISOR comprises an entire writing system with refills and washable wipers. The refills are water-based and adhere to all smooth surfaces and papers. Therefore they are suitable for whiteboards as well as flipchart-papers. They can instantly be used and also wiped off. A newly developed rotary mechanism makes changing of refills easy. The single writing systems can be connected in wall holders. A roll-stop prevents rolling away. In a refill-case the refills are protected from breakage. Removable, washable and exchangeable wipers make the writing system complete.
