I was worried because it was a Korean manufacturer, but I feel that I used it because the core does not shake well and it breaks well and it does not break easily. Depending on the lot, there is some variation in sharpness, but it is divisible within the error level. Considering the price, we judge it better than the domestic manufacturer.
