Yuxin Speed Stacking Cup, higher, faster and stronger
Large vent design
Challenge without limits and reach new realms
The ventilation holes can effectively reduce the friction on the air when the quick-stack cups are stacked at high speed to achieve high-speed and stable effects. Removing the cover can reveal a larger ventilation hole.
High speed and stability: The inner wall is smooth, which can effectively reduce friction, and the surface has a slightly frosted effect, making it more stable and less slippery.
Memory plastic: Made of hard recording plastic, it can quickly return to its original shape after being twisted.
Thickened cup lip: Thickened cup lip, finely made, different from ordinary cups, can achieve a more stable effect during the stacking process
