The toadstool is printed on a special polymer, then covered with resin, for a beautiful surface shine and to last you as long as possible.
 
Dimensions of the brooch approx.: width x height x depth approx.: 30x38x1.5 mm
 
dimensions and each piece may differ slightly from what you see in the picture, I usually make brooches after ordering, they are hand painted and that's what makes them original :-)
