Green elephant

So I would consider most of our toys to be pretty sustainable, safe, etc. I just ordered the green elephant stepping stone toys (Staplestein is out of our budget). I was really excited until I read that they are manufactured with the Temu dupes. They claim to be nontoxic EPP foam but I'm still so nervous that I am bringing something bad into my home. I'm also 8 months pregnant and a little extra suspicious/paranoid. They don't take refunds and I really am hoping they are ok. I emailed the company asking for safety/toxicity information, but I doubt they will have anything. Any reassurance or did I mess up?
