I’m pretty sure mine were made before they switched to the Chinese manufacturer. I bought a case of them like 3-4 years ago. Didn’t worry too much about using them. From what I understand, as long as it wasn’t made in China or Korea you should be fine. I think if it says made in USA or Thailand then its one of the good ones (supposedly made by HiFlo). I could be completely wrong, so do your own research of course. ?
