Tampons

So I'm on my period. I want to try tampons. I've had a few tampons since like 2014 and I move them around a lot. But not in the box I move them around in the little packages. I guess you could say a single wrapped tampon. I'm obsessed with period storages. I move the tampons in the wrappers all the time because I get new period supplies. And I opened a few but never used them and I'm planing on trying tampons for the first time tomorrow. Is it okay to use the tampons that I opened but I had them since 2014. HELP ME PLEASE!
Thank you for your time💜
