These are professional quality moulds, thick metal, beautifully patinated. The sort of moulds used to make the delicious individual tartes, such as tarte au citron, at the French Patisserie.
They look delightful with a tealight popped in for a festive French chic homestyle, the light reflects their répousse square design on the base.
The tins measure 9cm, 3.5" diameter and 1.75cm high and are sold in sets of 4.
There is also a set of 4 slightly smaller tins in the same design, measuring 8cm diameter, pictures on the left of the first picture.
