This is a set of 30ml Polo Ralph Lauren Eau de Toilettes.
Each lid has flaws, with the red and green one having small marks, several on the blue, and a scratch / dent on the black bottle. All of them appear to have been used. The blue bottle has most likely been used the most as it is three quarters full and has several scratches.
Each eau de toilette is 4x2.5x9.5cm. Polo Red and Polo Black were made in France, Polo and Polo Blue were made in the U.S.A.
