It cost 410 yen. It is not regular clay and is not scented.
Microwave heating times vary according to dough size. If you boil all of them at once, some of them would not become erasers, or eraser dough would stick together.

It's hard to work the dough in a place at low temperature. When you work the dough in a place at high temperature, it would be soft and stick together easily.
When you rub the dough parts, they just stick together on their own. (When you do it in a place at low temperature, it might not stick together because the dough would not be soft.)

I did it in cold winter. The dough didn't be soft enough and the dough parts didn't stick together well.

※ 個人の感想です。
この粘土は冬は固くてこねにくく、パーツがくっつきにくいので難しいです。夏は粘土が柔らかくてこねやすく、パーツがくっつきやすいので簡単に作れます。冬に作った今回は、粘土をこねて柔らかくしても、2つ目のパーツを作っている間に先に作ったパーツが冷えて固くなり、できあがった2つのパーツをこすり合わせてもくっつかなくて数回やり直しました。
