Van Aken International – Claytoon – Non-Hardening Modeling Clay – VA18158 – Cool – Green, Turquoise, Blue, Violet – 1 Pound Set (4-1/4 Pound Bars) – claymation, Gluten-Free, Non-Toxic

For my application I was looking for a modeling clay to establish cut lines when attaching two plastic pieces. This is just not the right clay for my purpose as the color transferred and stained test pieces of plastic (ABS and HDPE). A colorless version may work for me, though there is also an oily residue left over too. Just for clay models, this is a good choice, but still messy as the color transfers to you hands and to anything you touch until you wash your hands really well.

Stains everything it touches.

Works well and worth the money. Leaves a little color on hands but it's good quality otherwise.

When wetted down with water there is no way to scrub the essense of the clay off of my hands, no matter how and what soap type product I used....

It wasn't what I expected. It was very small and hard, I don't recommend this product especially for the cost.

This product was as claimed & was a big hit with my grandsons. Not greasy and easy to form, also holds it's shape

Used these so 6th graders could model land forms for their geography test

Using this to patch my clay collectables and even jewelry with stones missing.

good clay but leaves color

この商品をこんな風に使っている人も少ないかもしれません。私は発生生物学を研究している科学者です。具体的にはカエルのembryo（胚）の位置を固定するために使います。手で練るとかなり手に色が付くのですが、胚に対する毒性を見るとさほど色素そのものの危険性は高く無いと思われます。全部このような特殊な用途に使うのではなく、一部持ち帰って娘に遊ばせたのですが、手の染色具合がハンパでは無いので若干子供向けにはいかがなものかと思います。固くならない、という点に関しては間違いないですし、水に溶けないのでかのような特殊用途にも充分対応できます。適度に形を維持できるので通常の用途としても使い勝手はいいと思います。発色は良いのですが、手に色移りするということは色を混ぜる時に若干不安がありますね。
