Clay Toppers include ONLY the DIY clay piece of a DIY Clay Slime type. Sometimes, it's nice to have just the clay which is a bit buttery and easy to play with. You can also then mix it into any other slime base you may already have or make. Another fun thing to do is cover it with clear nail polish and let it dry to make what is known as a clay cracking piece. The shell hardens and you can smush it for a delicious crunch!
