Black silicone pads and a stainless steel design, the designers of these vacuum tumblers were inspired by car cylinders. The tumbler’s masculine appearance has adopted harmonious lines which make the product appeal to both men and women. The series consists of two models: while the tumbler features a wide lid, which opens with only one hand and ensures a secure grip when driving, the bottle-shaped model has a hook lid to prevent the spilling of drinks while on the move.
