Popular water bottles in America: This is a set of CORKCICLE and Tiger Corporation water bottles. The colors are cherry blossom pink, turquoise blue, and stainless steel silver, which are timeless. I mainly used them as water bottles for camping, for water, sparkling water (Tiger Corporation silver), cooking, and highballs. I've only used them a few times for camping, and they have been sterilized. The mouthpiece of the Tiger Corporation turquoise blue bottle is a straw type, and a new one is attached. I was using the regular type, but there were some scratches, so I replaced it with this type, which I bought for summer. I think it's also good for club activities. The Tiger Corporation silver water bottle, which can hold carbonated drinks, is also a great product for summer. In my opinion, they are all clean and in good condition. As you can see in the images, the inside is also very clean. Each has a capacity of about 500ml. No claims, no returns.
