Tips of Storage: In order to foam clay to have a better finish and longer-lasting flexibility, it can be sealed with plastic dip or put into a box. Air Dry Clay: The clay foam needs 24-48 hours to dry, depending on the thickness and volume. When foam clay has a moist feel, you can make it up at random and finish your crafts. After air drying, you can also carve and cut with a sharp knife to give full play to your cosplay artistic creation. Good Adhesion: Foam clay has 300 g and 500 g two sizes for you to choose from. Use foam clay to easily attach it to other surface types, such as foam, wood, tile, fabric, ceramics, etc. Great Flexible: In wet conditions, the moldable foam clay can adhere well to itself and EVA foam, but also can use hot glue/cement to obtain better adhesion. When foam clay dries, it still maintains a certain degree of flexibility, making it more ideal than paper clay or model clay. DIY Cosplay Foam Clay: The foam clay is lightweight and easy to shape. It can be stretched, carved, and pressed into the mold to create amazing decorations/details for your cosplay. Shape this high-density clay into any design you imagine! It can accommodate any crack, notch, knot, or shape your shape. Easily fill silicon mold.Educational Objective: Dexterity, Hand-Eye Coordination, Creative Skill. Item Weight: 500 Grams.
