They are designed to be trendy. It is also good and functional, which is deeply favored by numerous customers.The material is stainless steel 304 and all are mirror polished finish.But the texture is much different. The first one is for mosaic, and second one is wave, the last one is ripple.Maybe you cannot image all the effect and texture is handmade work, it is from our experienced master, forged that time by time.So sometimes you will find the handmade trace, it is normal. That is the value of handmade work sculptures.Please share your ideas.
