Quick question. So only the blue top sippy cup is safe to buy? The link goes to Amazon to a set of 4

Isn’t barium toxic?
Hi Amber – that’s a great question!
That is my understanding. There are different types of barium though. Based on the research I have done I am not comfortable with the scientific studies to date (I think there needs to be more research into potential barium toxicity in dishware and cookware.)

Would you say this is a safe sippy cup to buy?
I noticed that the product you tested says suncraft on the bottom, but the product in your affiliate link says sunzio. Do you know if they are the same thing? Thanks!
Hi, thank you so much for testing. I am a bit confused by the results, though. Is this a safe cup to buy and if so, are all colors safe? Is the affiliate link correct, since the brand name is different?
I also want to know if the Sunzio cup is the same as the Suncraft cup that was tested.
Oh! Interesting. It looks like they changed the linked product to another brand? Or changed the brand name. Sorry I can’t say for sure either way.
Wait, I’m confused, are you saying this cup is safe to use or not?
I’m sharing with you about the XRF detectable metals in each component so you can make informed decisions for your family – decisions based in science.
