Four dining room chairs from the Italian brand Softline, model Pauline.
Slight traces of use on the plastic, but this is only visible in certain light and (therefore difficult to photograph). 1 chair has a dull spot of 3 by 4 cm due to an overzealous cleaning lady, but this is not noticeable / disturbing in daily use (on the backrest of the first chair in video).
Purchased in 2008 for approximately 1,200 euros as a set, invoice no longer available. Price for the whole set, only for sale as a set.
