It came with a few nesting pieces going from a k cup style, fine mesh for instant coffee, and a larger cup for other things I’m not certain of.

The instant coffee mesh on it makes the water stay around the tea long enough for a pretty nice brew. If you add slightly more tea than needed, you can fill a cup with ice for perfect ice tea.

Same. I usually keep a couple sealed bags for an individual cup in my pack, so If I get the chance away from home, I can have some of the good stuff.

It’s gotten kind of expensive near me though, I need to find somewhere I can buy bulk loose tea.
