Van Aken Plastalina Modeling Clay - Gray, 1 lb, Modeling Clay

Very firm but loosens the more you use it.

Works very well for fidgety kids/students. My son's teacher originally bought these for her students. He makes little people, villages, whatever .... while also completing his school work. Because they worked so well for him for focus, I bought my own. I'd recommend not sharing this among multiple people. One block per child and label it (break them up).

Used for adding weight to a keyboard chassis. 1lb was more than enough and I was thankful I didn't have to purchase an excessive amount.

My daughter wanted this for Christmas because it doesn't dry up. She can continue to make new things over and over. She got this package of colored clay and gray clay.

No down side to this clay , easy to mold

I run a very busy precasting company and go through a lot of plastalina. This was a great product at a great price. I will be ordering much, much more!

Found it very difficult to mold as or is extremely hard even after a considerable amount of working. It also had an odd and unpleasant odor. It ended up in the trash.

This type of clay doesn't dry out or harden. Warm temperature environment would soften it, great for my art class project!
