2021 Snow Peak Stackable cups. The vacuum structure is insulated and the rim is designed with a thin opening of 0.8mm, which decreases the possibility of spilling with its wide cup. The wide and straight design can help lead the aroma of beer to move upwards, allowing both taste and smell sensory to be enjoyed at the same time. A non-slip and anti-falling soft plastic is specially set on the bottom to avoid falling. Available in four colors: silver, black, olive green and sand.
