Those are very stylish Japanese vintage style ceramic mugs with rust-glazed finishing. The mugs were handcrafted from high quality clay and were glazed at a very high firing temperature (1300 Celsius), the colors of the mug glaze are very beautiful, the silver grey is very subtle whereas the reddish yellow is a lot more vibrant.
I believe those handmade ceramic mugs will bring an organic, earthy feel to your morning ritual. It is a good purchase for any tea and coffee lovers and a perfect mug gift for your loved ones.
Those ceramic mugs are available in 4 styles and 2 glaze options, please refer to each style size in the pictures or as following.
Mug Care: Please do not use it for microwaving. Hand wash your mug with warm, soapy water and a soft sponge. After washing, let it dry off completely before placing in the kitchen cupboard.
