Crystal card kits are craft kits, ideal for children and adults, which enable you to make your own sparkly and beautiful crystal cards. The technique is similar to painting by numbers. Each crystal card design has a numbered, adhesive template. Using the amazing magic pencil (included), simply lift up the coloured crystals and place them on the corresponding numbered dots. They affix instantly! The technique is relaxing and therapeutic, and the result is a beautiful piece of rhinestone art which you can gift to loved ones.
