Lots of nice features! Introducing the cute water bottles I found at the 100-yen shop Ceria.
A product called "soft water bottle" designed in the form of soft serve ice cream, lemon, cassette tape, etc. It is made of polyethylene and has a flat bag shape, but it has a gusset and can hold plenty of water. The lid has a structure that makes it easy to drink directly, and the side of the bottle has a carabiner, making it convenient for the outdoors. If it is empty, it can be folded into a small size, so there is no need to worry about storage space. It is self-supporting when it is filled with water, so you can put it on the table and enjoy its cute appearance.

Due to the characteristics of the product, it is difficult to wash and dry it thoroughly, so it is safe to avoid using it for a long time as a beverage. Since it can be frozen, it is a good idea to use it as an ice pack for a cooler box or for watering flowers. If you see it at a 100-yen shop, why not buy one? The store I went to had two sizes (400ml (13.53us fl oz) and 500ml (16.91us fl oz)), and the price was 108 yen (tax included) each. It is not possible to add carbonated drinks, alcohol, dairy products, etc.
