My kids have a great time playing with clay. They can create several objects based on their imagination or from a picture. We do have some brands of clay as presence to them and we bought the others. Having more clay will be fun and to avoid the fight. Although it is kind of messy playing with clays I appreciate the fact that it enhances their creativity to form things on their own.Among the several brands of clays available, I do prefer Activity Centre Modeling Clay for my kids for their home and school use. It is not so soft and not that hard, just fine to deal with for my kids to form different shapes and objects they want to do. It does not stick to their hands and easy to clean. My kids have 10 different colors to play with to make their work colorful. It is AP Nontoxic as certified by the Art & Craft Materials Institute which makes it safer for my kids to play with.
They have used already our spare box so this coming school year we will need to buy four boxes: one box for each of them and the other two is for home use.
