These appliques are made of polyurethane resin. They are hard like thick plastic, don't break easily and can be flexed when heated up (hairdryer, heat gun, microwave), to a certain extent depending on thickness.

They come unpainted but can easily be painted as shown in the first photo, and glued on your home decor or furniture pieces. 

I've grouped them for purchase in sets so you can arrange them as shown, or to your own liking :-)
