Surat Hanunuo word 'Pinoy' (Filipino) Pin

It is an Abugida descended from the Brahmic scripts,closely related to Sulat tagalog,and is famous for being written vertical but written upward,rather than downward as nearly all other scripts (however,it is read horizontally left to right). It is usually written on Bamboo by incising characters with a knife. Most known Hanuno’o inscriptions are relatively recent because of the perishable nature of bamboo. It is therefore difficult to trace the history of the script.
