The Tea Spot is a wonderful company that makes these beautiful ceramic steeping mugs. Only they don't always keep the same color in production. So, Necessitea wiped them out of their black mug supply. Currently they will remain the same price but as the inventory diminishes the prices will go up since they can't be replaced until The Tea Spot decides to produce them again. Currently they have not indicated that black will be returning. They currently are producing these mugs in red and blue. Necessitea does not carry the mugs in any other colors and will continue to sell them in black until they are gone.
