This is a box of 33 packets of Ion Drink from Fine Co., Ltd., for 500ml each. The expiration date is August 1, 2027, which is almost 2 years from now, so you can rest assured (see the second photo). The taste is similar to sports drinks like Pocari Sweat or Aquarius. Of course, it's unopened and brand new. One box contains 33 powder sticks, and each stick is mixed with 500ml of water to drink. If you want to use it like an oral rehydration solution, you can use about 1/3 (about 150ml) of the water to get a similar concentration. Since it's 500ml per stick, it's the perfect amount to dissolve in a regular-sized plastic water bottle. It's equivalent to 33 bottles of 500ml, so dissolving it in water is a significant cost saving (buying 33 bottles of 500ml water would cost 3300 yen even if each bottle is 100 yen). One box contains 33 sticks, which is equivalent to over 8 bottles of 2-liter drinks, and over 16 bags of 1-liter powder. Many 1-liter powder products come in boxes of 5 bags, so this is equivalent to over 3 boxes. In recent years, scorching heat has become the norm every year, so staying hydrated is essential, and the stick type doesn't take up much storage space. There are still many hot days left, and it's good for next year too, and you can never have too much. Hydration is important even in winter, so you can also dissolve it in hot water and drink it hot. It's sugar-free, fat-free, and 94% calorie-off, making it perfect for those who are concerned about excessive sugar intake or weight. Free shipping (shipping included).
