I think these ones were from a X'mas season made by SIDUL. On the back tells you how to make a wrapping package for sweets.

A sugar maker, SIDUL, has done a series of portuguese traditional costumes from different regions.

On the back of "ALGARVE" one, it has a receip of Dom Rodrigo which is a traditional desert from the region.

Each NICOLA's package tell you the portuguese poplation in a different country. 

​"Only one portuguese lives in Sudan" apparently...

"Pacote de Açúcar"

(sugar packages) 

On the limited spaces of sugar packages, you see many different designs and sometimes with interesting information.

​I'm always looking forward to finding new one.
