(Regarding enameled products) As each piece is handmade, there may be some conditions in the manufacturing process, but this is not a defective product. Thank you for your understanding. The black dent on the edge of the pot is a dent where the pole and pot contact with the rotary base support the pot is applied.There are any products in the manufacturing process.It is absolutely no problem with the use. ● Pinholes, bubbles, and uneven colored enamel coating are done individually by hand, so there may be slight color unevenness, bubbles, and pinholes. This is not a problem with use. There may be slight gap between the lid and the pot itself, but it is not a defective product if it does not interfere with use.
