This 3 piece resin mold set is well constructed and made of durable silicone. We have made one of the molds and my daughter uses it as a trinket box. This could also be used for other purposes. The glitters are a great addition to this kit. All you need is the epoxy and supplies to mix/pour. This is guaranteed to provide fun for older kids and adults--no two boxes will be alike! Highly Recommend!
