I haven’t looked, but I don’t think I’ve seen any in Wegmans’ “free from” style dishwasher, clothes washer, or dish washing liquids

These were in clothes washing detergent. The internet says it can happen if it's subjected to very could conditions which could happen when in transit.

How interesting. I've never seen that.

And I discovered them when I tipped the nearly empty jug and they rattled!

I was about to ask, but you already answered my question.

Interesting!

That is weird.

heylisa: First time for me.

Godtess: Yes!

4jTan: I agree!

So strange

2xstitcher: Yes. Seems weird.

Yikes!

Ddaisy: Not harmful, just odd.

we ran into problems with screen printing paint for metal signs.
it got cold enough in transit to totally change it's behavior

DevSpamNull: Oh, same deal, I guess. Very interesting.
