Annett Bourquin and Kerstin Greve are designers from Lisbon, Portugal. Under the label of ANVE, they create objects that take their time, and become more beautiful with life.

Their Sacos de papel bags are particularly interesting. Although the association with an ordinary brown paper bag is easily made (Sacos de papel even means paper bags), rolling it up is actually a beautifully lo-fi and valid way to close a bag.

And of course it also creates a handle out of nothing; love it.
