Studio Aizawa ｜ Hot water bottle

Traditional hot water bottles were mainly made of tin or resin. Since they are used for long periods of time to hold hot water, the material will deteriorate over time. Stainless steel is highly corrosion-resistant, so it can be used for a long time. Stainless steel has better heat retention than other materials, and even after filling it with boiling water and leaving it for 24 hours, the water will remain at just under 40°C, which is enough temperature to wash your face the next morning.
