Tin box manufacturer in china£ºPure tin material has good ductility. It is called "Xiangxi" because of its distortion and sound. Handicrafts will be deformed after being twisted, so this method cannot be used when purchasing, but we can use a simpler method to "smell the sound": gently sweep the tin ware from the palm of your hand with your nails, and 97% of the tin ware has a clear metal sound and a short echo. 99.9% of the tin is not crisp and bright, and there is no echo. It is a superior tin ware.
