Great sake cups, see sakura flowers magically bloom! I studied abroad when I was in university, staying in Tokyo for two semesters a decade ago. Now living in San Francisco, I often miss the cherry blossoms I saw in spring in Japan. I saw this set of Magical Sakura colour-changing sake cups and had to have them! They are so beautiful. This is my favourite set of sake cups to show off when my family comes to visit! Simply the best purchase I have ever made, the look on everyone's face when these beautiful blossoms appear is priceless. Turn your dinner and drinks evening into a magic show! Amaze your guests with a whimsical magic trick that makes vibrant, colourful blossoms appear from the sky, while filling these traditional Japanese 'o-choko' 猪 口 Sakazuki cupswith your most prized sake. In Japan, very expensive premium sake is served cold, with your choice of Nigori or Ginjo, which has a smooth, delicate flavour and fuller flavours when served chilled. While traditional 'Junmaishu' or hot sake is best served warm. Here, we offer the original Magic Colour-changing sake cups that respond to cold or hot sake or even water/tea. How the reaction works COLD - Reacts only to COLD liquids. Sakura and Peach bloom RED, and the plum specifically only blooms RED in this set. Currently our most detailed colour change as seen in videos. HOT - Responds only to HOT liquids. All Sakura, Peach and Plum will change to a LIGHT pink blossom. DUAL (WARM & COLD) - Responds to SO MUCH WARM & COLD liquids. All Sakura, Peach and Plum will bloom LIGHTROZE when HOT and a detailed BLUE when COLD. A traditional masterpiece Crafted and hand-painted by local Japanese artisans, inspired by works of art painted by Kitagawa Utamaro. Each 'o-choko' (sake cup) Sakazuki is painted with a special non-toxic thermochromic pigment ink and then coated with a translucent food-grade ceramic glaze to seal the colour-changing ink. Colour changing function: the colour changes when the temperature of the hot colour changing cup is higher than 39 degrees, and the colour changes when the temperature of the cold colour changing cup is lower than 21 degrees. The pigment is: temperature-sensitive materials are painted on the cup body and coated with a clear glaze, the materials used are heat-sensitive materials, high temperature resistance of 320 degrees, non-toxic, BPA-free, lead-free, chrome-free and meets FDA / EU standards . Due to the delicate thermal reaction, there are cases where certain parts of the world are too hot or too cold, so the cups arrive completely blown out and activated from the box. In this case, we recommend serving them in another season or applying a heating or cooling method to return the cups to their original blank white with branches. Gentle hand washing is recommended to preserve the life of the cups and the ink design, dishwashing is not recommended.
