The season when you miss keen and chilled drinks with ice. I found a photogenic "ice" at PLAZA.
The "Sparkle Ice Cube" sold by the household goods brand "BRUNO" is a cold storage product with a jewel motif. Distilled water is contained in the polyethylene material, which can be frozen and used in place of ice. The price is 500 yen (excluding tax) for 10 pieces.
Freeze it in the freezer and put it in a cold drink to keep it cool without diluting the concentration. Even if you put it in a water bottle or a drink bottle, it will melt and the contents will not increase, so you can rest assured.
It seems that it can be used for keeping food and lunch boxes cold, but it does not melt for a long time because it melts for the same amount of time as ice. You can put it in a cooler box and bring it to a picnic or outdoors.
It is also economical to wash and use it repeatedly. The cool colors look great for the hot season!
