Yamada launch one hand iron wok (thickness 1.6mm) 27cm (Japan import / The package and the manual are written in Japanese)

I wasn't expecting this iron wok peeled off so quickly (if happening like this there will be whole on the bottom soon). I bought this for durability and uncoated option but the wok quality is very poor. I paid too much for this quality. Very unsatisfactory product compare to price.
