These items feature a vacuum-insulated structure all the way to the lid, which suppresses heat intrusion and cold air release from all directions, allowing them to maintain temperature for extended periods, offering outstanding heat and cold retention.

The "Hyotenka Keep Cylinder Ice Core" is a large-capacity type with approximately 2.3L, perfectly fitting 1.1L of convenience store ice. It can keep ice solid from morning until night, making it ideal not only as an ice bucket for dining tables but also for enjoying ice-based dishes like somen noodles or shaved ice outdoors. Furthermore, it can be used to transport ice for heatstroke prevention during sports or for first aid in case of injuries.

On the other hand, the "Hyotenka Keep Cylinder Chill Short" is a short type that is easy to use as a tumbler, with a capacity of approximately 440ml, perfectly fitting 200g of convenience store ice. It is convenient for cooling lukewarm drinks during sports spectating, hiking, or in saunas. It is also suitable for carrying cold foods like frozen fruits or frozen towels, and can even be used to keep cans and bottles cold or warm as they are.

Additionally, when used in conjunction with the separately sold "Baisoku Toketsu Hyotenka Pack Gap Bar," it can also keep ice cream bars cold.

The main body is made entirely of stainless steel, making it rust-resistant and less prone to odor transfer. It is easy to clean even after putting coffee or tea, and its wide-mouth structure makes maintenance simple. When the lid is closed, it seals tightly, preventing contents from spilling even when inverted, and the vacuum-insulated structure also prevents condensation, allowing for safe carrying in a bag. Since it supports both cold and hot retention, it can be used in a wide range of situations regardless of the season.

We invite you to try the two types of "Hyotenka Keep Cylinder" bottles, which offer excellent heat and cold retention with a vacuum structure extending to the lid, through the Makuake pre-sale, and utilize them not only for outdoor activities but also in your daily life and home.
