Steel, not titanium. No O-ring
As other buyers have noted, the metal is not titanium. The hardness and the smell indicate that the material is most likely a steel alloy. There is no o-ring, which is a significant deletion and an inconvenience. It makes no sense why this was not provided. If you want a steel capsule that is not water or air tight out of the box, this is the product for you.
