Mate made of 100% stainless steel. These models have the advantage that, thanks to the nature of their material, they are more hygienic, easy to clean and do not transmit the flavor of the container to the yerba mate. In addition to this, they do not need the curing process that pumpkin ones require. As with ceramic mates, the risk of the existence of fungi is eliminated (since it is resistant to humidity). Steel, in turn, is durable and allows the temperature of the mate to be maintained. We recommend this model to take everywhere and enjoy the mate ritual!
