Hilarius Design has developed together with PostNL, the Dutch Post Packet Service, an exceedingly strong product: the rectangular Viko tube. The Viko tube can be kept in a broadsheet edition and after simply putting it together can be handled perfectly in the sorting centre of PostNL.
The registered fastener no longer needs staplers or tape. Moreover you can mail at a lower price. Every print preferred is possible.
Get in touch if you prefer to order these Viko tubes in your own style.
