I thought that it looks good looking at Amazon’s products (links) from lifehacker’s articles (links), so I made an article. The image is from Amazon.
Good appearance, affordable price for 3,680 yen, it is quite good product with a size that does not take place 16 cm. It is made that the inside gets cold when you put the material and turn on the power. “With an original recipe, it is perfect for gifts.”
