Shenzhen is the brand of the band-a-ring towloon home, and i'm in thailand, where i collect the raw materials of the swallows and process them in my own factory.

At the source of origin, you control every link, from the beginning of the material to the processing, stereotyping, drying, disinfection and transport. 100% complete monitoring. This is the seventh year i've made a swallow nest, market chaos, a lot of bleaching, a lot of drying and picking, and a lot of glue, and a lot of sticky stuff coming into the market. It's hard to get 100% of a purely handy nest without the quality control of jue's place of origin
