Sixlets? is that what the top of santas had is?? I had wondered, although I've trusted some Wilton items in the past. Might be regional, but sometimes, there is a cross contamination warning, sometimes not, sometimes, if I remember correctly, there is a combo of USA and China manufacturing/packaging or visa versa, it seems on the label, and then I just give up. Not particularly trustful of China since the Melamine in the baby formula thing. (or "Mexico" on the label, for that matter, either) Just not enough oversight. I really cotton to "Made in Canada" though.
If I don't see a "cross contamination" warning and just an allergy warning, I'm still good with it. It's my impression they take a bit of pride in their allergy awareness and limits of labelling. But that's just me. No advice intended.
Oh, I found the valentine take out containers at both Michaels and Jewel. Probably paid through the wa-ha for it, but hey, I saved some fuel, and didn't get sucked into the decorating aisles at Hobby Lobby.
