Personally I wouldn't buy them just for the fact that they are made in Thailand. My kids know my stance on foods made in China and other similar places so they don't really complain much if they can't have something like this. I know that some Hershey is made in Mexico but that's pretty much where we draw the line.
btw I saw a Ring Pop display that said made in USA. I didn't look at the packaging or anything to see the ingredient list though but I seem to remember them being safe in the past (other than being made in China at that time).
