Flat beads are in the format of "Thickness x Width x Length". See diagram, eg Flat Oval, 6x17x26mm, Palmwood.
Some items have a slashed format such as 4/5. This means that the width of the beads is between 4 and 5 mm. Length for Heishi beads and Square Cut beads is not specified due to variance in the thickness of the natural item, eg sea shells and coconuts.
