This came up in my search for a tea baller, and in the image it looks like a ball, but it's not! My mistake for not making sure, but I really thought it was a mesh ball. It's just a strainer. The net doesn't go down very much, so it's not super useful for a herbal tea you want to infuse for a long time, which is all I drink. But it's cute, I like the little teapot design, so I'll keep it anyway, even if it's not very useful to me.
I bought it as an "add-on" item, but it was shipped separately, even though there was definitely room for it in the box the rest of my order came in. Defeats the purpose of an "add-on" item!
