I bought something interesting today.
It’s really ignorant, and there’s such a thing.
Stainless steel ice cubes.
The outside is stainless steel, there is liquid inside, not solid.
The temperature can be kept longer than expected.
This way, you don't have to worry about the taste of the drink. If you put more ordinary ice, it will dilute the drink, and this stainless steel ice will not.
A glass of beer is usually placed in three. A box of six is enough for two people.
The only problem is that if you are concerned about health issues, it is best to buy them for yourself.
