The Buydeem Mini Thermos Bottle is part of the BUYDEEM Creamy Insulation Series which is convenient to take-away. The 300ml capacity is suitable for daily commuting, and the small body can easily fit in a women's purse. Also, the inner liner of this vacuum cup uses an integrated stretching process instead of the more common welding process. Thanks to the stainless steel material, resistance to acid and alkali corrosion is greatly enhanced, so you can literally put any drink into it. This product comes in four colors: cozy green, duck yellow, dogwood pink, and a white that corresponds to all four seasons.
