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. Crystal card kits are also a great way of making DIY Christmas cards. Making a crystal card takes 30-45 minutes. They are suitable for ages 8 and up. These new Crystal Cards Kit use the same resin gems as the Crystal Art Kits, giving these cards a subtle shine. This card is 18 x 18cm in size.
