MarvisClassic Strong Mint Toothpaste

Seems to be conflicting answers about a metal or plastic tube. Can someone confirm this and the lid, please? Thanks!

I ordered this product twice, and both times it came without a seal. Obviously that's how the product comes. How to know it hasn't been tampered with?

They used to offer a version with fluoride. Why not now?

Is marvis 1.3 oz travel size in an aluminum tube or plastic tube ?
