What are those thread-like necklaces called?

[Brutalis]

I keep seeing these MLB players wearing them. They look like braided thread/yarn or something.

I ask cause my girl wants one. Know where I can find them? Online somewhere perhaps??

My older cousin told me that they are kind of like those new bracelets that everyone wears that make you more balanced, except this necklace gives you a higher pain tolerance or something. Not sure if its true or not

Yeah they're called phitens, outside of the look of it I don't think it really does much at all. Used to wear one but then stopped.

Yeah I wear one for baseball and every now and then just to do it.

They don't do anything to you lol. If anything, it's a placebo effect. But in reality, it just looks dope.
