Fishermen would bring their food rations for the day in a Cepu ke Laut, a circular wooden container that was lined with a banana leaf. The box had a tightfitting cover that was usually secured by a rope or a piece of wire. They were usually carved from a solid piece of lightwood such as Nangka or Angsana.
Surah Baqarah verse 154 is inscribed on the cepu cover.
