Kato Polyclay is known for strength and flexibility after curing, as well as its range of colors. All of the Kato clay colors are intermixable, giving you an almost endless array - from bright primaries to soft pastels and everything in between. Kato polymer clay can be stiff to work with at first, but its durability and colorfastness make it worth the effort.
Kato's Basic Conditioning Bar is a solid (easy to handle - no mess!) way to help condition stiff clay. Simply mix as needed with clay to soften. Cures strong and flexible.
