I'm assuming, based on your photo, that your brush is a Delong brand brush? Just Googled Delong and it appears that they are made in Shenyang China. (Edit: Just looked at original post and the Delong web link is posted there---!!!).
Nothing wrong with a brush made in China as long as their quality control and sanitation procedures are up to snuff. One serious problem with natural hair shaving brushes years ago was anthrax. That is why some older (antique) brushes had "sterilized" embossed on the handles to assure barbers, and customers, that the brush was safe.
Considering some of the manufacturing bloopers out of China lately (melamine in dog food, lead paint on childrens toys, and who knows what else...) I'm not sure I'd be comfortable using one of these brushes even though the pricing is tempting. At least not until I was assured that the factory is using standard sanitizing procedures.
If someone else has any more info regarding this, please share. In fact, I hope I'm completely wrong.
