The tit is a drawing printed on a special polymer, then covered with resin, for a beautiful surface shine and to last you as long as possible.
Each part of the double brooch has its own brooch bridge, so you can wear them together or separately.
Dimensions of the tit approx: width x height x depth approx: 32x43x1.5 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 :-)
