Review on Set Of 4 Kitchables Insulated Glass Tea Cups For Hot Tea - Durable Borosilicate Glass Mug - Elegant And Fancy Small Tea Cups (2.5Oz) by Floe Rankin

I have been using these cups for gong fu style tea brewing. I have a 90 ml gaiwan, and one of these cups holds the perfect amount of liquid.The cup stays cool to the touch and due to the curved design, I can fill these cups close to the brim and not have to worry about spilling it when I drink.The only negative is there is a small logo on the bottom of each cup which I can see through the bottom when drinking my tea.
