I don't know if you saw my post in TeaChat last night or not. For an interim solution, you might try RoT's disposable teabags
and teabag handle
. You can buy them as a set
I use them all the time and they work really well. The handle is plastic but the bags are just paper. You can also buy a nicer handle that is made out of metal (but not, I don't think, from RoT).
RoT also offers a tea strainer
that may meet your needs, although this is a new offering of theirs and I've not tried it. It comes in two
Here's a large metal infuser
they offer as well. This may be exactly what you're looking for.
