Can you Help with this Weird Airsoft BB brand?

I just ordered a DE UMP M89 airsoft gun off of amazon.com, and it came with the gun and in two SEPARATE packages were 5000 .20g bbs and a quick loader. On the description it said that the BBs were white and came from Airsplat.com, but when i got them they were all green and made by a Chinese brand that google doesn't have anything on. The brand is Qiaowei BBs. If you know what they are plz help!!!
