The 2013 series introduced hybrid substrate to Solomon Islands currency — a composite of paper and polymer layers developed by De La Rue under their DuraNote brand. The format was adopted partly in response to the Pacific climate, where high humidity accelerates the deterioration of conventional cotton-paper notes faster than in temperate-zone economies.

Pick 35 is notably light on published security features relative to what De La Rue typically applies to Pacific island issues of this denomination, with catalog records citing only the watermark — worth noting for authentication purposes.
