These are a Northeastern style hot pot style noodle sold under the brand "KLKW" (an English Acronym for the Chinese translation "Chopsticks come, chopsticks go"). There is next to no information about these guys on the internet, but they seem to make a lot of raw products.

These noodles are manufactured by Jilian Pan Jia Food Co, LTD. in Qian'an county Jilin province.

I got these for about $AUD4.00
