February, when the cold days continue. Even if you buy hot coffee at a convenience store, it tends to get slimy quickly. Introducing the "Vacuum Convenience Cup [Regular]" goods that will help you with such problems.
A pearl metal product that can hold a cup of coffee bought at a convenience store. The stainless steel vacuum insulation structure suppresses heat conduction, so the drink inside can be kept warm and cold.
When I try adding 7-Eleven hot coffee (regular), it feels just right in size. When I drank it little by little in a heated room, I was able to enjoy the moderate warmth until about an hour and a half later. It seems that the speed of cooling will increase in cold outdoors, but it is helpful to be able to maintain the taste for as long as possible.
The approximate size is 80 mm in outer diameter and 95 mm in height, and it can be set in a car drink holder. Depending on the type of convenience store coffee, it may not fit well, but you can also put drinks directly, so why not use it as your own cup?
It is sold on various mail-order sites, and the price range is around 500 to 1,000 yen. In addition to brown, there are ivory colors, and larger sister products are also available.
