The calabash is the optimal accessory to use! Why? Like any plant, mate swells with infusion. It needs space to release all its flavors. By opting for this accessory, the mate thus has all the space necessary to brew freely. With its aesthetic and sleek design, this double-walled stainless steel isothermal calabash equipped with a watertight lid, will allow you to keep your mate warm for long hours. It is ideal for consumption throughout the day whether you are in the office or on the go. Unlike traditional gourds (wood, squash...) that absorb the flavors of mate and require special maintenance, stainless steel is a neutral material and allows the mixing of flavors without altering the taste. Also neutral for your health, it is guaranteed BPA free. Keep warm for 6 hours.
