I've included some microwave cleaning supplies with my soup jar. To show the size of the soup jar, I've added a photo comparing it to a THERMOS soup jar and a can of beer. Just to be clear, neither the THERMOS soup jar nor the can of beer are included in the product. ＜Original Food Pot＞ Vacuum-insulated double-wall construction for heat and cold retention. A convenient size at 350ml. I'm currently using a different food pot, and here's how I use it. For your reference! I put 2 tablespoons of pearl barley into the empty food pot. I prepare my favorite ochazuke seasoning. I take this to work. 3 hours before eating, I pour hot water into the food pot in the company's pantry. The purpose is to warm the food pot and soak the pearl barley. I wait for about 3 minutes. By the way, I go to the restroom during this time. I carefully discard the hot water from the food pot so as not to spill the pearl barley. I add hot water again. The amount of hot water is to your liking, but I usually use about 200ml. Before eating, I add the ochazuke seasoning and mix it in! It's quite hot, so I eat it while blowing on it. 〈Microwave Steam Cleaner〉 A human-shaped plastic cleaning tool - Color: Purple - Design: Human-shaped design - Material: Plastic - Usage: Cleaning tool The images are cited from Amazon.
