What kind did you get?  Welcome to #teachain 🫖 

Being a tea nerd, I have different choices for different situations. 
Here are a couple favorite choices.  

Not pictured:

1. A stainless steel bombilla like is used for maté when you just wanna throw leaves in your cup. 

2. A stainless tea ball with a spring closure and a weighty charm on the end of the chain. By spring closure I mean there is a little spring that slides onto the “beaks” of each clamshell half, holding them together. It took getting used to but now I like this more than the normal way these are closed, with a little arc of metal binding a section of the two sides together. 
The charm keeps the thing from flipping around when you add water. https://image.nostr.build/365f07e8535d6a59910745ba859b35ea96cb9cd6755c6f6807b97c9a7859e368.jpg https://image.nostr.build/d48d0ac1e9ee9c105f625426eff72dd9ec8f05527d17de3fa00952168cd93567.jpg  

 I say not pictured because I couldn’t find a suitable picture. They are also favored choices I use frequently. 

 Those matching tea sets are lovely, but... They are always too small. My mugs hold over 750ml of water. I hate small cups. 😅

I've seen the ball type before. I've not seen any that were made well enough to last, IMO.

Just some random black tea from an Asian market. Not like I know any better, but it will likely be better than much if the stuff that I drink.  

 I can talk tea if you want. 
If you want to send a pic of the box, I’m curious. 
Go back to the Asian market and see if they sell stuff that is like a tea ball but a little larger. Meant to hold soup ingredients. May be sturdier and or better suited to a large mug. I also use them to infuse mulled cider/wine with spices. 
This spring style ball I’m talking about seems sturdier which is why I now prefer it to the normal tea ball with the latch. I’ll try to remember to snap a pic when I  am home. 

 I'll message you on simplex. 

It'll be a while until I go back to that place. The local h-mart is smaller and not as well stocked.
