This is a set of only 6 pieces. The detachable handle is not included. The instruction manual, usage guide, and instructions for attaching the glass lid knob are included (photos ③④⑤). Part of the usage guide is missing, but it does not hinder reading. The warranty period has expired. I previously received a 9-piece set here. I only used the frying pan, and the pots have remained unused. I would like to pass them on to someone who wants them before they become a burden. They will be delivered in the original box. The gaps left by the missing frying pan and detachable handle will be filled with packing material to prevent damage. Although they are new, please understand that they have been stored at home before purchasing. There are no smokers or pets. Recycled materials may be used for packaging. Thank you for your understanding.
