These are Ryukyu glass drinking glasses. I received them as a souvenir several years ago and I think I used them once. Because they are handmade, there are individual differences and the sizes vary. Please check the images. Outer dimensions: Pink: Diameter approx. 7.5cm x Height approx. 7.8cm Blue: Diameter approx. 7.6cm x Height approx. 8.2cm If you have any questions, please feel free to ask in the comments. Also, as I don't have the box or outer packaging, I will likely wrap them in newspaper and cushioning material for shipping. Thank you for your understanding.
