Thanks to NotMattWong for starting this poll! We've contacted the vendor on your behalf and they've made the SpaceCase 4-Piece Titanium Grinder available.
The space case is $64.99, not $110. May want to fix that. Even the 3.5 inch one is only $100.
Edit: The titanium 3.5 inch does come to $109, so I was wrong, my bad. I think we should probably have more than one option though if the Space Case does win. For example, Titanium and Aluminum ones, 2.5 inch and 3.5 inch each.
