The 3 piece coaste molds for casting in rsin are quality and exactly what I was looking for! I love working with resin and these will be wonderful crafts to make and give away. These demold easily and are also easy to clean! The molds take their original shape when I am finished and are ready for the next time I want to use them. I haven't used all of them but the coaster set is amazing looking after it's done! So many possibilities!
