• Please do not store under high temperature, humidity, and avoid direct sunlight.
• The appropriate temperature is under 25°C for storage.
• Please keep the boxes sealed when not in use.
• Once clay is removed from the box, we recommend that clay should be used as soon as possible to avoid deterioration.

Do not use microwave ovens to heat clay! Our clays are designed to be evenly heated at the exact temperature of 60°C or 58°C, which can't be achieved with microwaves. Microwaves heat from the core of the clay, which as it warms, expands in volume. As a result, if the clay's core rapidly warms while the surface remains hard, an explosion may occur.

For the NS60 Series, the oil and wax components are designed to be warmed up to 60°C. At this designated temperature, our clays soften for proper use. Heating our clays above or below the specified temperatures can result in changes to the physical properties of our clay, which is not ideal for use.

• Proper warming time is 3 hours when using controlled temperatures.
• Do not attempt to warm these clays with less time and higher temperature.

Low temperature burns may occur on skin if applying clay with bare hands. We recommend using latex gloves, or similar types of gloves.

Each type (even types with the same working temperature) has different properties. If mixing different clays for use, color inconsistency, cracking, peeling etc. may occur after molding. We do not recommend mixing our clays.

It is important that clay must be adhered well. In order to do so, you should be careful when you apply clay to make sure not to leave any air bubbles between applied clay and clay surface. If leaving any air bubbles, it might cause the crack. If possible, we recommend to use heat gun to warm up the surface before applying clay.

Yes, our clay can be recycled and reused after kneading and de-airing through our clay shaper. Please note that mixing clay with other contaminants will compromise the quality of the clay.
Compared to new clay, recycled clay has the following characteristics and features:

• Physically, recycled clay becomes harder, heavier, drier and loses some of its tackiness.
• Recycled clay may become darker after the recycling process.
• Clay can be recycled a few times at most; however, we do not have a standard measurement of times that our clay can be recycled.

Our clay is not designed to be directly painted on. Directly painting the model is not recommended because solvents in paint can cause the clay surface to melt. However, our "Clay Modeling Film" is crafted specifically to be used to color industrial clay models.

Our clay does not contain any sulfur. Thus, it is possible to dispose of our clay by incineration.

*It is hazardous to dispose of any clay containing sulfur (even small amounts) by incineration. We strongly advise against doing so.
