This porcelain strainer works great. Drains well even with tea from a big gaiwan. This was something I was concerned about before purchase. The stand that can be purchased together have 3 holes at the bottom, which is hard to see from pictures. Sometimes small pieces of tea does get clogged in a few holes but easy to clean with a kitchen faucet sprayer.
