Yes, I made a pun, but I couldn't resist. Am I 40 years old? Yup. Did I buy these for myself? I did. Am I wearing one of the necklaces and bracelets right this second?
...Yes. Yes I am.
Confession time: I've only recently realized that one of my main stims/ coping mechanisms when getting overloaded is chewing/ gritting my teeth, so I've only just started to gather things I can chew on, or at least have between my teeth to remind me not to clench my jaw. These necklaces and bracelets are brilliant for that. If you're like me, you probably grew up in the era where phones still had spiral cords, and whenever you were talking on the phone, you wound the cord around your finger until your mom pointed out your fingertip was turning blue. Then you unwound it, waited five minutes... and did it again.
These give that same vibe. My only complaint is that the spiral is so tight, you can't really do that easily, so one of the main potential selling points is missed slightly. However, you still can do that, just not as effectively. That being said, you can still chew on them, pluck at them, twist them, run your fingers over them, all sorts of things, and even adult teeth have difficulty damaging them.
One thing I especially love is the hygiene aspect. I was worried that, since they're around your wrist/ neck, they would be germ traps, but found quickly that they're very simple to clean under the tap. simply give them a scrub and rinse, dry, and reuse. If they were just that tiny bit more flexible/ larger on the spiral, I would give these 5 stars.
