ON℃ZONE Cool-Sip Insulated Flask 330ML BLACK
ON℃ZONE Cool-Sip Insulated Flask 330ml in Black. It seals shut for carrying, making it suitable for work, days out and travel.
The Cool-Sip range is made by Japan’s ON℃ZONE for people who can’t drink things piping hot. An ordinary mug cools down too quickly, while a vacuum flask keeps a drink scalding for far too long, and neither is easy to sip from. Cool-Sip combines a heat-absorbing material inside the cup body with a vacuum structure, so about three minutes after you pour in a hot drink it settles to a drinkable temperature of around 77℃, after which the vacuum layer keeps it above roughly 58℃ even an hour later, staying at its best from the first sip to the last.
The wide mouth is easy to clean, and it works for cold drinks too, keeping them cool for a long time. Whether you are making coffee at the office, enjoying tea at home, or serving older family members and children who dislike hot drinks, there is no more blowing and waiting.
