| Reverse description | The reverse is dominated by a large intaglio-style vignette of the São Tomé tree frog (Hyperolius thomensis) rendered in green and gold tones at the right, set against a fine guilloche underprint in teal and green. To the left of centre, a detailed map of the islands of São Tomé and Príncipe identifies principal towns and the equator line. A small Charaxes barnsi butterfly vignette appears at the lower left alongside the large numeral '20', with 'VINTE DOBRAS' inscribed vertically on the dark security band at left and the bank title running along the lower margin. |

The 2016 series marked a significant redesign effort for the Banco Central de São Tomé e Príncipe, with Thomas De La Rue retained as printer — a relationship the bank has maintained across multiple series. The 20 Dobras sits at the low end of the denomination range, and in a small island economy with limited cash infrastructure, low-value notes of this type see disproportionately heavy use and wear out quickly.
Security provision is modest: watermark and thread only, consistent with the note's place in the series hierarchy.
