This company has been my favorite tea strainer producer since I got involved in tea. They’re sturdy, don’t corrode, and are a perfect size to use with the glass carafes I use (that are also for sale on this site). I buy these from webshops and retail tea shops whenever I see them and put them on this site for your convenience, I think the company might be on its way out of business as they’ve been getting hard to find lately.
