Great quality, size, and excellent for all occasions/sessions. I love the width of sizes with this set. It definitely allows for the option to have a tiny "sample" session, to a shared session (2-3), or one larger session 3+ (or for the hardcore tea consumer). These are quite lovely, with vibrant colors. Definitely would recommend to anyone if you're looking for a good set of gaiwans, and are uncertain of how large you want your shared and/or single tea sesssion to be.
I was excited to see a merchant offer different sized gaiwans for sale in one set. This is like a happy family of gaiwans!
Are they made from high-end porcelain manufactured in Jingdezhen? No. But, I was looking for functional, beautiful, everyday teaware. I love the lightweight feel in my hands, even with the large 200mL sized gaiwan. Highly recommended if you want to have a variety of gaiwan sizes to suit your needs for a specific gong fu session (e.g., gong fu for one, two, or more).
