For our products to be enjoyed by many people for a long time, we seek a higher safety standard in every product field.
Our clay products are tested by public organizations and regulated under the safety standard of each product field.
Some products have safety certifications such as the AP seal and the ST seal.
It is a certification seal launched by the ACMI (Art and Creative Materials Institute). The products are tested for acute and chronic toxicity, eye or skin irritation, cancer-causing substances, allergies, hormone-disrupting substances and other possible hazards to the human body. These tests are conducted at the Duke University Medical Center by trained toxicologists, which makes this seal extremely reliable.
