The peta is a stiff beaded cap from the Kelabit Highlands of Sarawak. Its front field is packed with ba'o rawir — 15–25 mm burnt-orange glass tubes laid in radial rows — edged with yellow alai ma'un peanut beads and flanked by counted stripe panels in turquoise, brick red, white and black.

The glass is antique trade stock, priced by age and provenance rather than looks. Thirty yellow peanut beads once equalled a buffalo; an antique peta still reaches RM30,000. This system treats every bead the way its owners do: as a count, a type name and a value, never as ornament.
