Here’s the (good) plastic ones, unfortunately unavailable https://www.amazon.com/dp/B06XCBTNBQ, and these are the metal ones I got https://www.amazon.com/dp/B07HMF9KCM?. I ordered both after having lost most of a bad plastic batch I had ordered (150, I think there might be a couple left). But if you don’t want to risk it, I’d go straight to metal.
