【Difficult to Restock】We've only managed to get a small quantity, and there will be no restock. We've taken actual photos in a Japanese photography studio, so please purchase based on the pictures. This is a one-of-a-kind item. 【Oil Clock】There is an item called an "oil clock." An oil clock is a type of clock that uses a special liquid (oil) to display the time. Unlike ordinary clocks, the hands and numbers of an oil clock appear to float within the liquid. It uses a special viscous liquid (generally petroleum-based) and indicates the passage of time through friction and vibration. 【User Experience】My 1.5-year-old grandchild even takes them to bed to play with. Since it was a set of 4, I used them for birthday presents for my child's friends and for my own home. I was able to use them in various ways. The colors are beautiful, and they were very happy with the unusual choice. Because the body is not deep, it is easy to tip over, but it doesn't break even if it falls, and there's no problem when displaying it. I would like to use them again if I have the opportunity to send small gifts. 【Actual Product Photography & Domestic Shipping】Actual product photography + inspection + repair. Although manufactured overseas, a Japanese photographer in a domestic studio photographs the actual product, and staff inspect and repair the product at the time of shipment. 【Specifications】13.5 x 5.2 CM, set of 4. The time varies by a few seconds depending on how it's flipped, approximately 1 minute. #Pee's Mercari Selection
