Glasses susceptible to fracture due to residual strain at the edge! If you have one, contact your seller

In September 2022, NCAC received a request for conducting a product test from a consumer saying "A glass was broken when I was washing it. My hand was injured. Would you investigate why the glass was broken?" When checking the glasses, NCAC found that they had residual strain¹ at the edge probably caused by inadequacy in the manufacturing process. We've learned that when such a glass is scratched at the edge or subject to external force, it can be broken more easily than glasses not having residual strain. Besides, this incident is included in the news release² on the Consumer Affairs Agency website as a serious product accident under the Consumer Product Safety Act and as a serious accident under the Consumer Safety Act.

In addition, it has been reportedly said that the import company of the products found a similar problem. If you have a glass named "aurora glass", stop using it and contact the PAL CO., LTD.
